76mm (3 Inch) Mortice Deadlocks: Questions

Which size deadlock do I need?

If you are replacing a lock, measure the backset (from the door edge to the centre of the keyhole) and match it: 45mm for the 2 1/2" (64mm) deadlocks and 57mm for the 3" (76mm) deadlocks.

5 lever or Euro deadlock?

A 5 lever deadlock is worked by its own key and takes a keyhole escutcheon on each side of the door. A Euro deadlock has no key of its own: it takes a Euro cylinder or thumbturn cylinder, sold separately, so you can choose the key and turn arrangement.
