Gate lock guide: Why you should choose a bolt-on gate lock

If you look closely at the gates in your street, you will find bolt-on gate locks a common sight on metal gates.

Bolt-on gate locks are fixed to the frame of the gate with bolts or screws as shown below. They are usually installed symmetrically on the gate frame and are visible from both the inside and outside.

Bolt-on locks don’t require any cutting or welding of the gate making them a convenient lock choice for many installers.

What are the main benefits of a bolt-on gate lock?

Less work:

As you do not need to cut or weld your gate frame, you only need to drill a few holes, which is much easier and quicker to do. Installing such a lock is literally tightening up the screws. Imagine, how much time you will save if you do not need to clean and brush your welds!
We have actually timed how long it took one of our colleagues to install such a lock, you can see our video here:

The symmetry:

Bolt-on gate locks are installed symmetrically, which not only looks great, but allows you to have the same gate wing for both left-opening or right-opening situations. Which, again, saves time and helps you to avoid costly mistakes.

Easy installation:

As we discussed above, a bolt-on gate lock is very easy to install. This means that anyone can do it. You don’t need to have a skilled welder or cut a precise slot in the gate frame. In fact, these bolt-on gate locks are notoriously popular amongst the DIY-enthusiasts as well as fabricators.

Economies of scale:

When working with bolt-on locks, there are usually different models available that fit in the same way. Thanks to this you can prepare all your gate frames beforehand in the same way. This means you can have a standard production process and gain from economies of scale.

You can then stock these gates without risking any mismatch. Your customer can still get a ton of personalisation in the last stage of the selection, since any of your locks would fit in that gate regardless.

Early preparation:

A quick delivery process can be a huge advantage in the fencing market where seasonality plays a big role, and the summers can get really busy fast.

Therefore, having a quick process can help you better manage your work, handle more projects and get more done!

With a bolt-on gate lock, you can have the holes pre-drilled in the factory even before choosing the colour, and the installation of any bolt-on lock will be done quickly and precisely on site.

Where are bolt-on locks most commonly used?

Forged gates. You can see a lot of bolt-on locks used on forged gates that have flat bars like the below example.

The open design of the gate invites for a visible lock box. In addition, other locks might not be suitable for this style of metal gates. For example, the flat bars are not suitable for mortice locks due to the limited thickness of the bars. A weld-in lock box requires quite a bit of extra work in such a gate and doesn’t have any obvious advantages, so bolt-on gate locks remain a great solution for this type of metal gate.

Open-space fencing. Gates with mesh panels, metal bars or palisade fencing are often seen in the cities, around sports grounds or industry terrains. Such fencing does not obstruct the view too much and allows for visibly ‘open space’ – hence the name – while still requiring a quality working gate.

As these gates typically have simple, minimalistic design, bolt-on locks fit right in with their easy, standardised installation and symmetrical look.

Large perimeter projects. Building on the previous point, open-space fencing is often used around stadiums, city parks, local building developments, inside or outside logistic centres and large machine parks.

An important characteristic of such projects is that they need to be uniform and very cost-effective. Function takes precedence over appearance.

As discussed above, a bolt-on gate lock works great with economies of scale, both during production and installation, so this is a great option in such a situation.

How does a bolt-on gate lock compare to other lock types?

Mortice locks:

Compared to mortice locks, bolt-on gate locks are much easier to install, since the mortice lock require very precise cut-outs on 3 sides of the frame tube. It is therefore rather difficult to retrofit a mortice lock onto an existing gate. The bolt-on lock, on the other hand, can be installed by almost anyone on a new or existing gate.

However, mortice locks offer an aesthetic look, where the infill on both the gate and the rest of the fence look uniform, without the lock or anything else breaking the lines.

This can be especially important on gates that are filled up with composite or timber; as some bolt-on locks have rounded shape, it can be difficult to make a precise cut-out in the infill.

Weld-in locks:

A bolt-on gate lock will have a fixed width and size, which can be harder to install on some design-forward realisations, or which can look out of place in some cases.

Weld-in locks usually come with welding boxes in different thickness, which allows you to have very clean, uniform lines.

Some manufacturers favour the weld-in locks above mortice locks too, since they would only need to cut out one square piece of the gate frame, and not the precise cut-outs on 3 sides required for mortice locks.

Asymmetrical surface-fixed locks:

There is a variety of locks in the market that are fixed on the gate on one side (usually, on the inside), so they are not visible at all from the street. This is typically done on solid gates that do not allow the installation of the bolt-on lock.

The advantage of such a solution is that you have no gap between your gate and your post, comparable to your inside door, where it is impossible to peak in from the outside.

This is, however, also the biggest disadvantage: gates are constantly exposed to the outside elements and need some space to crip and expand to be able to function properly. There are not a lot of solutions in the market that are designed with this in mind, so this can result in a badly functioning gate.

Why choose a bolt-on lock?

The above is a few of the reasons why our customers love the bolt-on locks and our own Superlock range remains one of our bestsellers. But if your gate hardware heart leans towards weld-in or mortice locks, there are plenty of reasons why these types are favoured. You can find out why in our other gate lock guides on weld-in locks and mortice locks.

Gate lock guide: Why you should choose a weld-in gate lock

You might be wondering how do you weld a lock? We’re here to help answer that!

A weld-in gate lock essentially consists of a weldable box and an internal lock mechanism. The weldable box has been prepared to fit the lock mechanism, which can be installed after the lock has been welded.

How to install a weld-in gate lock

In order to install a weldable lock, you have to measure the gate frame and cut out a piece of it to fit the weld in lock box. Once this has been done, the lock box (without the lock mechanism inside) is welded into place. The entire gate frame can then be sent off to be galvanised and painted.

Once the gate has been painted, you can install the lock mechanism.

This is usually done with the supplied fixing bolts to fix the lock mechanism in place within the weld in lock box. Now the gate frame is ready to be installed in its final place with the lock in place and fully integrated in the gate frame.

Here are some benefits of a weld-in gate lock

This process might seem a bit lengthy, so why should you use a weld-in lock on your gate?

1. Straight forward manufacture: As mentioned above, it is easy enough to weld in a square (or a rectangular) box to the frame, without needing to provide precise cut-outs.
2. Design: The weldable lock boxes can easily be integrated with the gate design. As the weld-in box is treated and painted together with the rest of the gate, the whole look is more harmonious.
3. Easy replacement: Should you need to replace the lock mechanism; this can easily be achieved. Just remove the lock mechanism while the weld-in box stays safely in the frame.
4. Back set: A weld-in box allows you to have a bigger back set size, which can be beneficial for large gates that require a wide stop plate.
5. Durability: As the lock mechanism is safely protected from all sides against water and dirt, the lock can last longer.

When to use a weld-in gate lock?

Generally speaking, a weld-in box is a labour-intensive alternative that offers a deep integration of the lock box and the gate frame.

Thanks to this, such weld-in locks are used in situations where the look of the gate plays a large role. Forged gates with unique designs, specifically crafted cover plates or modern-style gates with decorative steel sheets as infill would all often use such weld-in locks.

In comparison

The main alternative to a weld-in gate lock is using an insert gate lock, which is also integrated into the gate. For some projects though, insert gate locks might be deemed too small or not secure enough, or alternatively, would be impossible to install due to technical limitations.

Mortice locks require precise cut-outs in the gate frame, which isn’t always possible to do easily. Mortice locks do traditionally have a shorter back set, which doesn’t always work on larger gates. Therefore, weld-in locks provide a great, durable alternative and a clean finished look for your gate.

Additionally, very large gates constructed with larger box section tubes could also benefit from using the weld-in fence gate lock. The latch on bolt-on locks might not be long enough, and the back set on the insert lock might not be sufficient. In this case, the weld-in lock option is the best alternative for these larger industrial gates.

It goes without saying that bolt-on locks are much easier to install. However, those only come in one width, while a weld-in gate lock can fit the exact width of the gate frame, providing a clean visual line.

Gate lock guide: Why you should choose a morticed gate lock

Everyone has come across a mortice lock because they are commonly used on regular doors. Using this type of locks on gates, however, has its own benefits and disadvantages.

Read on as we go through what a mortice lock is, where it can be used and how it compares to other lock types.

What is a morticed gate lock and when should I use it?

If you already know what a mortice lock is, you can skip this part and go straight to the next where we discuss the benefits of this lock type.

For those who aren’t aware, a morticed gate lock is known as an insert lock. This lock type is mortised into a slot in the gate frame, which hides the actual internal lock mechanism within the gate frame. You will therefore only see the handles and cylinder when the gate is locked. This makes it a very inconspicuous lock, and popular for that exact reason.

What are the benefits of a morticed gate lock?

1. Inobtrusive: As we have already covered, the lock blends in thanks to the way it’s installed. This means they can be used on a variety of gate designs without sticking out. This allows you to use different types of infills, offering your customers a wide range of designs and materials for their gates.
2. Customisations: You can keep the same lock and offer an array of different handles and cover plates, so that your customers can go wild with their design choices, while your lock – and your work process – stay the same.

Where are these locks used?

1. Doors: this is pretty obvious, but many gates are manufactured in exactly the same configurations as inside doors, therefore, the locking system stayed the same.
2. Wooden gates: the most common use for a mortice gate lock is wooden gates and frames. There aren’t too many options for such gates other than sliding bolts, surface-fixed locks, and mortice gate locks.
3. Solid gates: gates with composite or timber infill are often equipped with mortice locks. This allows you to keep the design of the gate uniform, as you do not need to make a larger cut in the infill.

How do mortice gate locks compare to other alternatives?

First alternative is a morticed door lock designed for inside use. A lock is a lock, right? However, your inside door is not influenced by the weather and other elements, so the requirements to the hardware are not the same.

You have probably encountered gates that are “locked”, but can be easily open with a simple push? This is due to inadequate hardware.

As any materials shrink and expand due to hot weather, rain, snow and other elements, your gate can change shape quite a bit, but the lock needs to stay securely closed at all times. Therefore, you need a bigger latch and adjusted inside mechanics.

Moreover, the inside and outside parts of the lock need to be designed to withstand the weather – otherwise, it will go rusty and start jamming in no time. Mortice locks designed specifically for outdoor use is therefore the recommended option.

Another alternative is a bolt-on gate lock. The mortice gate lock requires three precise cut-outs on three sides of the frame to be installed, while bolt-on locks require just a few holes through the gate frame. They are therefore much easier to install than a mortice lock.

Compared to a mortice lock, bolt-on locks are bulkier, more visible and can prove more complicated if you need to cut infill around them. Most bolt-on locks do come in different types, such as digital locks or quick exit pads, offering wider flexibility.

Weld-in locks are also used often for gates that have a particular design. When a forged gate is constructed out of flat metal bars rather than box section, a weld-in lock could potentially be the only option. Mortice locks require a certain thickness in order to fit within the box section. They therefore can’t be used on frames that are smaller. For example, the ML4 requires at least a 40mm box section.

Alternatively, a weld-in lock can be used to make sure the lock box is the same width as the box section.

A morticed gate lock is obviously easier to install in such cases, as it does not require any welding, but still requires precision cuts.

Gate locks with code, panic exit or key? Different types of locks for gates

Not sure what gate locks with code or key are? Or what the difference between bolt-on locks and mortice locks is? It can be confusing as there are a few different types of gate locks depending on different categories.

Read on below as we cover:

Different types of gate locks based on installation:

Locks can be categorised in different types of installations. The material of your gate influences which of the below lock types you can use, as some of these won’t work for all gate materials. You can’t use a weld in lock on a wooden gate for example.

Note that the below categories aren’t necessarily mutually exclusive; i.e. you can have gate locks with code that bolt on or are surface fixed. So, one lock can be in a few of the below categories.

Bolt on locks

Bolt-on locks are locks that are fixed to the gate by being bolted on. They commonly require you to drill holes through the front profile of the gate through which they are installed with the supplied fixings. As shown below, they sit between the external frame of the gate and the internal bars.

Bolt-on locks are therefore mainly used on gates with a metal frame where a space can be created within the gate for the lock to be installed. If having a solid infill gate, you would need to cut a hole for the bolt-on lock to sit in which can make it more of a challenge to install the lock. The Gatemaster Superlock can be a great option for these scenarios with its slim case and removable locking bolt, meaning it can be fitted into very tight spaces. This range includes gate locks with code, key access and quick exits. See how easy it is to install in this video.

Bolt-on locks are useful for retrofitting to gates and can easily be replaced, if necessary, as most of them will use the same fixing holes.

Weldable locks

Surface-fixed locks

For a simple, yet secure solution for your garden gate you can get surface-fixed gate locks with code, which can be installed quickly on your garden gate. We recommend using a keyless combination lock for wooden gates as it is a convenient solution and easy to use too. Read more about our Gatemaster options here.

Mortice locks

A mortice lock is a lock that is installed in a cut-out slot in the gate. They can be installed on both timber and metal gates, but they require a bit more gate preparation to install for both materials.

A mortice lock is a good solution for when you want an inconspicuous gate lock but don’t want to have to weld in a lock case. But time is money, so depending on the time you want to spend on installations and preparations, you might want to consider if a quick fit bolt-on lock is more suitable!

Different types of gate locks based on functions:

In addition to the installation process, locks are categorised based on the actual lock functions they have. Which one you choose depends on the needs and usage of the gate, so read on below to get the main features of deadlocks, latching locks and locks that can do both.

Deadlocking locks

Latching locks

Combined latching and deadlocking locks

Now we get to the good part! Some locks have a combined function and is able to both latch and deadlock.

Different types of gate locks based on access:

The final grouping, we will cover today is based on the access (and sometimes exit) functions of the lock.

Gate locks with key

Gate locks with code

Locks with keypad access can either be electronic or mechanical, both of which have their benefits (you can read more about that here).

Gate locks with push pads

So, there you have it: some main categories of locks you will find and their main features.

Everything you need to know about heavy-duty gate hinges

What are heavy-duty gate hinges?

Let’s start with the basics.

Heavy-duty gate hinges generally refer to a hinge that is designed to work for gates that carry a lot of weight due to their construction or size. This can be anything from a large bi-folding gate on an industrial unit or a heavy metal frame gate with wooden cladding. Both of these can weigh a lot and some hinges are simply not built to sustain this kind of loading.

That is why some hinges are labelled “heavy-duty” or “extra heavy-duty” even.

What makes a gate hinge heavy-duty?

There are many factors that can make a hinge more suitable for heavy gates and separate them from the rest of the hinges on the market. Below are some common characteristics of heavy-duty gate hinges on the market, so consider these when researching.

• Material: It might be an obvious one, but the material has to be of a certain strength. Steel and stainless steel are the most common materials as they are strong and durable.
• Construction: Due to the amount of force these hinges experience, a heavy-duty gate hinge has to be designed specially to accommodate the force of the gate. This is especially true for wide gates as the wider the gate, the more force the top hinge will experience.
• Size: It is natural that the most heavy-duty gate hinges are larger so they can hold more. But you can still find smaller hinges like universal hinges or flag hinges that are heavy-duty due to the material they are made of. So don’t let the size fool you!
• Weight limits: Heavy-duty hinges will have gone through strenuous testing cycles to establish the weight they can carry while still opening and closing the gate reliably. Understandably, despite being heavy-duty, all hinges have a limit, and, in this case, it will be a maximum weight that they can carry safely without having a negative impact on the performance and safety of the gate. Note that some hinges have this limit stated as pairs, meaning it will take two hinges to carry this weight and still function properly.
• Grease points: Maintenance is important for a large gate and the hinges are no exception. Depending on the usage level, a heavy-duty gate hinge will often require lubrication on a regular basis. Having a hinge that has built-in grease points can save you time (and a mess) when carrying out the maintenance. The built-in grease points will take the oil right to where it is needed and means you don’t have to take the hinges apart to carry out maintenance.
• Friction: With the force of a heavy gate, the hinges will experience a lot of friction when operated. Using a low friction hinge is therefore advised for heavy gates. Low friction can be achieved by using a brass bearing or a similar bearing device between other metals. Brass is known for its low friction capabilities and is commonly used to minimise resistance.
• Adjustability: This isn’t something that is necessary for a hinge to be heavy-duty, however using adjustable heavy duty gate hinges will make your life easier when installing. An adjustable hinge will make it possible to fine-tune the installation on site and have tolerance for the gap between the gate and gate post.

When should you use heavy-duty gate hinges?

Although heavy-duty gate hinges sound a treat, we don’t recommend using them on gates where it isn’t necessary. For lighter gates such as smaller garden gates, side gates or light single leaf gates, you might not need to go for heavy-duty. We do recommend you always check the capability and strength of the hinges to make sure they are suitable for your gate.

Heavy-duty gate hinges are really marketed towards larger, heavier gates that are commonly found on wide entrances or industrial areas where lorries need access for instance.

Obviously, the bigger the gate leaf is, the more weight and pressure on the hinges. If your gate is particularly heavy, you should therefore look into a heavy-duty hinge.

What types of heavy-duty gate hinges are there?

Heavy duty hinges for gates come in many shapes and sizes, and you can find a heavy-duty option for most standard hinges out there. This included bullet hinges, flag hinges, weld-on hinges, pivot hinges, the list goes on.

Check with your supplier if you can get a heavy-duty option of your preferred hinge. And always, remember to make sure the hinges you choose are suitable for the weight and size of your gate.

Latch length: How long are the latch bolts on our bolt-on locks?

We often get asked questions regarding the latch lengths for our bolt-on locks:

• How long is it?
• How much does it throw?
• How much will it stick out?

To make an easy overview of the different measurements above, we have created this guide for our bolt-on lock ranges – the Superlock and the Select Pro range.

Below you will find a drawing outlining the different key measurements to know about latch bolts and dead bolts as well as a table overview with all the measurements for our locks.

The table is split into the lock variation as we have two sizes:

1. 10-30mm gate frames
2. 40-60mm gate frames

When checking the dimensions for your lock, please check the product code and size for the right dimensions.

Deadbolt and latch length (bolt-on locks)

The actual dimensions that the latch will protrude from the front plate of the lock are shown in the diagram and chart below.

Dimension A in the below overview shows the dead bolt/latch bolt dimensions from the front of the bolt-on lock and through the gate frame when the lock isn’t operated (resting). All our bolts are adjustable by simply twisting the bolt in or out and locking in place with the supplied allen key. In the table further down you can find the minimum and maximum parameters of the bolts based on their adjustability.

Dimension B is the latching movement. This is how much the latch retracts when the handle is operated, pulling the latch back. The latching movement enables the gate to be pushed shut as the bolt will retract as it hits the striker and then spring out into the keep or post, holding it closed.

Dimension C is then the deadlocking (extending) movement and only applies to the locks that can be deadbolted extra. When turning the key to deadlock the gate, the dead bolt will extend this much into the gate post.

Please find all the measurements in the two tables below. Note that these only apply to our bolt-on locks in the Superlock and the Select Pro ranges.
