The Union 2277 3 Lever Mortice Sashlock is a reliable security solution designed for internal timber doors, offering a dual-action mechanism that combines a deadbolt and a latch for versatile daily use. It is ideal for homeowners and carpenters looking for a standard-duty locking system for doors up to 54mm thick; however, because it is a 3-lever lock, it is intended for low-to-medium security areas rather than high-security external entrance doors.

The Union 2277 is primarily designed for internal timber doors. For exterior doors, a higher lever count or BS-rated lock is recommended.
No, the mechanism is specifically rated for doors up to 54mm thick.
The unit is supplied with 2 steel nickel-plated keys.
The rollers rotate if a saw blade is used against the bolt, preventing the teeth of the saw from gaining purchase.
Yes, the lock casing is pre-pierced to accommodate standard bolt-through door furniture.
Check that the door is properly aligned with the striking plate; if the deadbolt is rubbing against the frame, adjust the striking plate position.
Inspect the spindle connection and ensure the bolt-through furniture is tightened correctly to the door face.
Verify the striking plate is correctly recessed into the door frame so the latch can fully extend into the keep.
To install, mark the door edge for the lock body and drill the necessary holes for the keyhole and the lever handle spindle. Ensure the mortice is deep enough to accommodate the full body of the lock. This model is designed for timber doors up to 54mm thick. To maintain performance, lightly lubricate the deadbolt and latch with a non-acidic dry lubricant once every 12 months to prevent sticking. Avoid using heavy grease, which can attract dust and debris inside the mechanism.
