Yale P77 Traditional Nightlatch 60mm Backset Brasslux Finish

The Yale 77 Series Traditional Nightlatch is a classic, reliable lock designed for exterior doors. It operates with a key from the outside and a knob from the inside, providing secure locking with a deadlocking snib function that can hold back or deadlock the latch internally. This model is compatible with doors that require a 60mm backset and is finished with a hardened brass case in Brasslux and a polished brass cylinder. It is supplied with two keys and an external cylinder (model 1109). The nightlatch is intended for surface mounting on external doors and is not recommended for glass panelled doors unless used with a 5-lever mortice lock. Additional details include internal snib operation to engage the deadlock, and a rim cylinder operated by key from the outside, with standard security components and a two-year guarantee in some variants.
