Yale P-77 Traditional Night Latch, 60mm Backset, Satin Chrome

Yale Traditional Night Latch

The Yale Traditional Night Latch provides a standard security solution for inward-opening timber doors in residential and light commercial environments. This surface-mounted rim lock features a 60mm backset, making it the industry standard for replacement or new installations on wooden frames. The unit utilizes a 5-pin rim cylinder to ensure reliable mechanical operation and basic pick resistance for perimeter security.

Built for the Job

Contractors and facility managers specify this hardware for secondary security on external doors or primary locking on internal utility rooms. The design allows for rapid installation on timber doors ranging from 32mm to 57mm in thickness. Because the main body sits on the internal face of the door, it minimizes the amount of material removed from the door core, preserving structural integrity compared to deep mortice installs.

• Secondary security for front and back timber entrance doors.

• Locking solution for shared residential hallways and storage areas.

• Retrofit upgrades where existing rim locks require replacement.
