Frequently Asked Questions

This is a 5-lever mortice sash lock — a lock that combines a latch (for normal door closing) and a deadbolt (for full security), all built into one lock case. It’s designed for traditional wooden doors (external front/back doors).

A 5-lever mortice lock uses five internal levers that must all align perfectly for the lock to open. This mechanism provides strong resistance to picking, drilling, and forced entry, making it a highly secure option for external doors.

This lock is suitable for solid timber doors that can accommodate a mortice cut (i.e. a slot for the lock case and deadbolt). It is generally not suitable for uPVC or composite doors which use different locking mechanisms.

Using a BS 3621 5-lever mortice lock adds significant security to your home. It meets the gold-standard for lock security for external doors — offering enhanced resistance against burglary attempts and helping meet many home insurance criteria.
