The UAP+ half cylinder is the best choice for inexpensive home security installation. Created in accordance with the British Standards Kitemark, and also awarded the "Secured by Design" approval by the Association of Police Officers, the high quality 6 pin Kitemarked euro half cylinder can be fitted to any external door in order to ward off criminals that attempt to use the most popular break-in methods.

Each half cylinder is packed full of security features, and is part of UAP's super smooth cylinders using the Chris Belcher designed anti-bump timing pin system. This very clever system uses nickel plated hardened steel key pins and driver pins, which gives the anti-drill feature we wanted to incorporate. The Patented timing pins are designed to interrupt the timing of the pins when bumped, and it is highly effective. And because we use special pins rather than trap pins, we do not have a high expense to get this anti-bump feature! The timing pins have inbuilt anti-picks, and mushroom driver pins, which makes them highly effective against picking.

The cylinders also have a sacrificial cut line on them. If force is applied to the end of the cylinder in an attempt to break the cylinder to gain access, on standard cylinders, the weakest part of the cylinder is the screw hole which is in the centre of the cylinder (as there is less metal here). When force is applied, the cylinder will break away at this screw hole, making it very easy to manipulate the cylinder into opening. On the UAP Double Kitemarked Euro Cylinder, the cylinder will break away to the sacrificial cut line only, leaving the locking mechanism intact. If the cylinder is broken at this sacrificial cut line, the last 2 pins in the chamber remain in the cylinder, meaning that the cylinder can still be locks and unlocked with the key.

We have in-house locksmiths which offer you the option to have keyed alike cylinders, or create customised and complex mastersuite systems.

Technical Info:

The cylinder has a sacrificial cut line, so when force is applied to the end,
the cylinder will break away to the sacrificial cut line only, leaving the remaining cylinder operational and the locking mechanism intact.

The cylinder has a unique and patented anti-bump system which does not use trap pins. This system makes the turning of the cylinder key extra smooth.

4 x hardened steel anti-drill pins are in each side of the cylinder. Plus all moving pins are nickel plated hardened steel 50 HRC minimum.

Minimum of 3 anti-pick pins in each side of the cylinder makes it extremely difficult for a common burglar to pick the cylinder.


testing icon

At UAP we are constantly striving to improve on the products we already supply as well as develop new, pioneering ranges and practical product solutions.

With an in house testing centre and product developer, each stage of the development process is thorough, from the initial design right down to the final product. In house 3D printing technology allows for further and more precise advancement of our products which are then expertly manufactured and put through stringent testing conditions using in house test equipment – ensuring all products are designed to the highest standards:

Cylinder Cycle Machine

This sophisticated machine tests the rotational operation of cylinder locks, ensuring a lock will continue to function even after being used in thousands of openings. It replicates the action of a key being inserted into the cylinder and it being turned, just as a product would be operated when fitted into a door. The product is tested to 100,000 repetitions to ensure it continues to function even after thousands of turns. It allows UAP to perform tests in accordance with BS EN 1303:2015 standards.

Cylinder Snapping Test

In accordance with PAS24, the test challenges the security features of a cylinder. An attempt is made to gain access through the cylinder by defeating its protective features, and then applying twisting or bending force to snap the cylinder and access its mechanism. Typically, the handle will first be ripped off, and then mole grips are used to try and make a larger hole around the cylinder. The cylinder is then snapped and attempts are made to turn the cam. A tester has 3 minutes in total to remove all protective hardware and defeat the cylinder, and only certain tools can be used if it cannot be done in this time then the cylinder will pass.

 Salt Spray Test

This machine tests the corrosion resistance of the door locks. The salt spray cabinet produces a corrosive environment, by releasing a dense saline fog into the chamber which the door locks are exposed to. This creates an accelerated corrosion of the door lock and allows us to test how well the lock would stand up in harsher environments.

All Weather Machine

When placed in the all-weather machine, the door locks are subjected to conditions including high UV exposure using a Xenon Arc Lamp which will accelerate UV degradation and measure how well a door lock can last in extreme conditions. Other conditions such as rain and extreme heat can be generated by the machine to expose the door lock to all kinds of environments. This allows us to continually improve the door locks and make them so they last longer in all kinds of different environments.
