Upright Non British Standard 5 Lever 2″ Mortice Deadlock

The Willenhall M4 series mortice deadlock features an “upright design” which mirrors the case size of a normal sash lock. The location where the spindle would normally sit is a round hole.

This is a unique upright mortice deadlock that features a 33mm backset and a 50mm case width. This narrow case depth makes it perfect for use on glass doors or doors with narrow stiles. It is supplied with 2 keys.

These locks do not meet the requirements of British Standard BS3621:2007.

In line with a number of other 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.

The deadbolt throws 12mm and features hardened pins to protect against sawing attack.

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 striking box in a grey finish.

Suitable for use on doors up to 50mm 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 steel 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.

Should you require more than one lock to work on the same set of keys, these locks can be keyed alike by our inhouse locksmith team. We can typically dispatch the same day (larger quantities may require longer).
