British Standard 5 Lever Mortice Deadlock

The British Standard TSS BS3621 mortice dead lock is our most competitive mortice deadlock. It combines quality and value to offer a compelling proposition.

These locks meet the requirements of British Standard BS3621:2007. To meet this standard, products undergo rigorous testing. Featuring 5 levers, anti drill and anti saw features, these are a high quality and high security mortice lock. The case has an anti-drill hardened plate, which makes it robust and provides additional protection against attack

In line with a number of other BS3621 mortice locks, these locks feature a black lock case but they have unique measurements that identify them from other mortice locks. Please refer to the line drawing for details.

This mortice lock BS3621 is available in polished brass, polished chrome or satin chrome colours.

To meet the requirements of British Standard BS3621, the deadbolt throws at least 20mm from the body of the lock to ensure positive deadlocking and additional resistance against attack.

The deadbolt features anti saw pins in a solid deadbolt.

The deadbolt can be locked and unlocked from either side by use of the key.

This lock is supplied with 2 key hole escutcheons, in a matching finish to the lock for both the internal and external sides of the door. It also comes with a security striking box (to meet the requirements of BS3621) in a finish to match the faceplate.

Suitable for use on doors up to 54mm thick. The thickness of the door is determined by the length of the keys. If you require this lock to be fitted to a very thick door, we may be able to supply extra long keys. Please contact us for more details.

These locks are not handed and can be used on doors hinged on the left or right, which open inwards or outwards.
