Yale Deadlocking Nightlatch - Silver - 630085001162

Use the internal lockable handle. Turning the key in the outside cylinder after closing the door will also deadlock the handle.

The snib button allows you to deadlock the latch from the inside, preventing the door from being opened with a key or handle.

This narrow design variant has a 40mm backset.

It is supplied with a Yale 1109 5 pin cylinder.

Occasionally lubricate the cylinder and moving parts with a suitable lock lubricant. Clean the lock with a soft, damp cloth to remove any dirt or debris.

The product is backed by a two-year manufacturer's mechanical guarantee.

Lubricate the cylinder with a lock-specific lubricant. If the problem persists, check for any obstructions or damage to the cylinder.

Ensure the door frame and door are aligned correctly. Check for any obstructions preventing the latch from fully engaging. Contact a professional if the problem persists.

Check the alignment of the lock and the door frame. Lubricate the moving parts of the lock.
