Zanda Narrow Sliding Door Mortice Lock 30mm Backset Stainless Steel

The Zanda Narrow Sliding Door Mortice Lock is engineered specifically for aluminium joinery and narrow stile doors. With a 30mm backset and 47mm case size, it fits where standard mortice locks will not, giving you a secure locking solution for sliding doors with tight frame profiles.

How a mortice lock works

A mortice lock sits inside a pocket cut into the door edge, allowing the lock body to sit flush within the door itself. This delivers a stronger, more secure installation compared to surface-mounted options. The latch retracts when you turn the knob or lever from either side, whilst the deadbolt is extended or retracted using a key from outside or a turn knob from inside.
