1. What is backset?
Backset is the distance from the door edge to the centre of the keyhole or handle. Two popular sizes are 44mm (64mm case size) and 57mm (76mm case size).
2. Which lock do I need?
There are various lock options available for our handles, choosing the right one depends on where and how the locks will be used.
For example
A latch would be used when you need no security and just wish to ‘latch’ in a closed position. Lever handles or a knob can operate the latch.
A roller catch would be used where you have a fixed handle and wish to ‘latch’ a door in a closed position. This is commonly used with pull handles, fixed knobs, or fixed lever handles.
A sashlock would be used when you wished to lock and latch a door in the closed position.
A deadlock works independently from your handles and can be used to secure a door. This can be used in conjunction with a sashlock to add additional security.
A bathroom lock is used on a bathroom door, the spring latch is operated by a handle or knob from either side, and a privacy bolt is operated by a turn and release.
