Bolt Through Latches

Bolt through latches are essential for doors on which you are fitting handles or knobs with bolt through fixings.

This type of mortice latch has additional piercings in the case which are there for the bolt through fixings included with the handles or knobs, to pass through. Door handles and door knobs fitted in this way are more secure and will last longer with every day use than if they are just face fixed to the door.
