Mortice Deadlocks

This old style Union deadlock does not comply to current British Standards so should only be used as a like for like replacement. For current British Standard version see Union 3G114E.

This is probably our most highly recommended deadlock, built to current British Standards, this top of the range Union 3G114E is a proven work horse. Providing the highest levels of security and the best of build qualities, this is the benchmark all others work towards.

Due to its custom case size the 3G110 is usually utilised as a like for like replacement. Although not made to British Standards we have found this to be one of the best deadlocks around and our expert team of Master Locksmiths would recommend it highly.
