It is a surface-mounted lock that latches as the door closes, opens by key outside and uses a knob or lever inside.
Automatic Latching with Keyed Access
Night latches mount to the inside face of a timber door and engage automatically when the door closes. A key operates the outside cylinder, while an internal knob or lever releases the latch from inside.
Check the backset, door thickness, handing and security rating before ordering. Some models include deadlocking or snib functions, but the exact operation should be confirmed from the product specification. Compare other entrance hardware in the locks and latches range.
A standard night latch may not satisfy an insurer as the only front-door lock. A separate mortice lock may also be required. Check the door condition, reinforce loose fixing points and confirm that suitable door hinges keep the latch aligned. Matching door furniture completes the opening.
