The Union StrongBolt group offers our most comprehensive range of door locks including 5 lever, 3 lever, bathroom locks and Euro and Oval cylinder lock cases.

The Union StrongBolt series is known for its superior strength. They have been tested to last in excess of 200,000 latch operations and in excess of 50,000 deadbolt operations and is therefore covered by an extraordinary 10 year manufacturers guarantee.

5 Lever Locks: The locks included in this group exceed the requirements of BS3621:2007 insurance approval with extra security measures in place such as anti drill plates, hardened steel rollers and a 20mm bolt projection. We have produced a handy video to show you how to fit a 5 lever deadlock.

3 Lever Locks: These locks are best used for internal applications rather than a final exit front or back door due to a lower security level offered. The Union J2203 StrongBolt 3 Lever Sashlock and the Union J2103 Strongbolt Deadlock are both available with a 68mm or 81mm case depth and with either a polished brass or stainless steel finish.

Bathroom locks: Specifically designed for use on a bathroom door with a handle and thumbturn rather than a conventional key lock. To watch a video showing how to fit the Union J22WC StrongBolt Bathroom Lock click here.

Euro and Oval cylinder lock cases: These locks are operated by a cylinder lock rather than levers and are compatible for use with any oval cylinder or Euro profile cylinder.
