What should I check before ordering a new door lock?

The most important measurements are the lock Backset and the lock handle centres (the distance from the centre of the handle spindle to the centre of the barrel). Please remember to check your gearbox against all of the measurements (you will need to remove the lock from the door to get accurate measurements).

The centre latch is non-handed, it can easily be reversed by following the instructions below.

  • Undo the screw located in the end of the latch.
  • Rotate the latch 180°.
  • Slide the latch back in.
  • Replace and tighten the screw.
