The Yale 77 Series Traditional Nightlatch is designed for homeowners and tenants seeking a classic, reliable security solution for timber front doors. Its primary benefit is the combination of convenient key-operated external access and internal manual snib control, though users should note it is intended for use on internal or inward-opening external timber doors rather than high-security composite or uPVC entry points.

No, the Yale 77 Series is specifically designed for timber doors and is not compatible with standard uPVC multi-point locking profiles.
The backset is the distance from the edge of the door to the center of the keyhole; 60mm is the industry standard for this model.
Yes, it is a nightlatch, meaning the door will latch shut automatically when closed, but it requires a key to open from the outside unless the snib is held back.
Yes, the 1109 external cylinder is a replaceable part if your keys are lost or the mechanism becomes worn.
You can use the snib feature to retract and hold the latch bolt in the open position, allowing the door to swing freely.
Check if the strike plate is misaligned or if the door has swollen, causing friction against the latch bolt.
Use a graphite-based lubricant and ensure the cylinder is free from debris; avoid forceful turning.
Verify that the internal screws securing the lock body to the door are tight.
This nightlatch is strictly for timber doors with a 60mm backset requirement. During installation, ensure the keep is aligned precisely with the latch to prevent friction or misalignment. Periodically apply a light, non-greasy lubricant to the internal latch bolt to maintain smooth operation. Avoid using heavy oils that might attract dust and debris. If the key becomes difficult to turn, check for obstruction in the cylinder and ensure the door is properly hung to prevent pressure on the bolt mechanism.
