Ultion Locks

Ultion Locks

All Doors supplied and installed by Radiance Doors are fitted with the Ultion Cylinder, accepted as the most secure keyed cylinder on the market.

We can also retro-fit these cylinders to your existing Composite or PVC Doors (where compatable), giving instant enhanced security.


A good lock is not enough.

Your door may look great, feel solid, and have a great multi-point lock, but what is the point if it can be disabled in a few seconds via an inadequate cylinder lock?

Here are four reasons why Ultion is different:

1/ Hidden attack lock

When Ultion detects an attack, it activates Lockdown Mode. A hidden firing pin in Ultion’s core secures the central cam and stops the intruder being able to open the door.

2/ Unbeaten in every test, literally

As well as being approved by the Police and achieving the highest Kitemark star rating Ultion is tested by locksmiths with the Master Locksmith Association and is accredited with their highest standard. Sold Secure Diamond.

3/ 294,970 key combinations

Most security locks have only 5 or 6 pins. Ultion uses 11. This means that Ultion creates nearly 3 times the amount of key combinations required for the highest standard.

4/ 20-point drill protection

Both ends of every Ultion lock feature 20 hardened steel pins and plates each one positioned precisely to protect your lock from a drill attack.
