Hardware Retro Fit British Standard Mortice Deadlock

This British Standard Zoo ZBS mortice deadlock 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.

In line with a number of other BS3621 mortice locks, these locks feature a silver lock case but they have unique measurements that identify them from other mortice locks. While the case width features standard 67mm (2.5″) and 79mm (3″) sizes, the backset measures just 40mm on the 67mm width case and 53mm on the 79mm width case. Please refer to the line drawing for details.

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 also has anti saw features.

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 matching finish to the lock 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.

Supplied with 2 brass keys as standard. We can cut additional keys for this lock, just select whether you’d prefer genuine or copy key blanks and the quantity required from the associated products on this page.
