Most internal doors which don't require locking are fitted with either a Tubular Latch or Motice Latch. When deciding which type of lock or latch you require, you will need to consider the purpose of the door it will be fitted on. For doors that require locking we offer Mortice Sashlocks, Deadlocks and Bathroom Locks.
