There are several different types of locks for external gates and they of course have certain features, which will determine the best lock for your gate.

In this article, we will explain the benefits of bolt-on gate locks and compare our two most popular ranges – the Select Pro and the Superlock.

What is a bolt-on gate lock?

The term ‘bolt-on’ is used for gate locks that are installed by bolting it to the gate through the gate frame as shown in the picture below.

The installation method is what differentiates a bolt-on lock and other metal gate locks. We have a quick overview of the differences in installation methods below:

  • Weld-in locks: These are welded into the gate frame. A section of the gate frame is either cut out or left out to fit the lock case. The lock case from the weld-in lock is then welded into the gate frame, which is then treated or powder-coated. The internal lock mechanism is then installed and the lock has become one with the gate frame.
  • Mortice or insert locks: Similar to a weld-in lock, an insert lock is integrated with the gate frame. In this case though, a slot is cut out of the gate frame to suit the insert lock. Once completed, the lock can be installed and now sits within the gate frame.
  • Surface-fixed locks: These are very similar to bolt-on locks as they are also simply bolted to the gate. The difference is how though. A surface-fixed lock sits on either side of the gate and is commonly used on solid infill, composite or wooden gates. It basically clamps the gate.

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

Less time, less work

With bolt-on metal gate locks, the main benefit is the simple and straight-forward installation. As mentioned above, bolt-on locks are installed by fixing them to the ate frame as shown below. The lock doesn’t sit within the actual frame but is attached to it. They are therefore commonly used on metal gates like mesh gate or bars.

Thanks to the simple installation, it won’t take you hours to install. Just drill the required fixing holes as instructed and bolt the lock to the frame with the fixings supplied. If you want to see for yourself, check out this video showing how the Superlock range is installed!


Most bolt-on lock ranges for metal gates will have a variety of access types to choose from. These will all be installed the same way within each range. So, you can comfortably prepare your gates before knowing if your customer needs a keypad or key access lock (provided they are from the same brand and range of course). The installation will be the same! This is useful when you have found a brand you like. You can now prepare your gates to the same lock without wasting any gates or time. Useful to do before the busy season kicks in properly!

It can also be good when working on larger fencing projects. You can manufacture all gates in the same way, but the customer can decide last minute if they want a quick exit push pad lock instead of a key to no extra cost or wasted time for you.

The two ranges of locks are safe options when it comes to securely lock your gate. Both ranges of locks have been manufactured to grant your gate optimal security, giving them equal levels of security.

Resistance to corrosion

The Select Pro and Superlock locks are all corrosion proof and will resist outdoor conditions. They have both been tested in harsh conditions to ensure longevity. The key difference is that the Superlock is mostly stainless steel whereas the Select Pro insides are electro-galvanised steel – stainless steel is often seen as a more marine grade option.

Easy to fit and adjustable

All the Gatemaster locks, without exception, have been specially manufactured with the fitter in mind. The whole process of installing any of these locks on the gate is simple, whether it is about bolting them on or welding them in. The latch bolts and deadbolts are all adjustable, for a precise fitting on site.

Support plates included

Both ranges come with their set of support plates when you purchase a lock. These plates reduce wear on the locks and increase their life significantly.

No power needed (for the digital versions)

All the Select Pro and Superlock digital locks are using mechanical keypads, which means no power is needed to use them. They are all extremely easy to fit as well, which makes them the simplest way to gain keyless entry to your property.

Simple and easy to use

Both lock ranges are easy and simple to use and have a light-touch deadlocking and latching action. They are suitable for disabled and elderly people as a result.

Multiple styles of handles available

When choosing your lock, if it has been built to be used with a handle, you will have the choice of a variety of styles to go with your gate. Straight, levers, twisted, ornamental, are all various styles available for you to choose from.


The design differences between the Select Pro and Superlock:

On one side, the Select Pro’s unique square shape has been particularly well-received by a lot of manufacturers. The shape makes them easy to work with and to incorporate into a lot of gate designs. On the other side, the Superlock’s case has the advantage of only being 70mm deep, smaller in comparison to most gate locks on the market.

Both the Select Pro and the Superlock ranges have a separate latch bolt and deadbolt, which is the more commonly seen design on the market. These bolts are completely removable, which means you can take them off to slide the case and body of the lock in position on the gate and then secure the bolts to ensure a precise and simple fitting.

In conclusion, the two ranges share a lot of key common points that make Gatemaster the trusted manufacturer we know. The differences mainly come from the size and shape of the locks within each range. Which one will work the best for you depends on your gate and the style you want it to have.
