Locking Bathroom Door Sashlock Latch - Silver - 64mm

You'll typically need a screwdriver, possibly a drill, and a measuring tape.

The 64mm dimension refers to the backset, which is the distance from the edge of the door to the center of the keyhole or turn.

Measure from the edge of the door to the center of the keyhole or the spindle hole (where the handle goes).

No, this latch is specifically designed for interior bathroom doors. Exterior doors require more robust locking mechanisms.

Ensure you are using the correct screws provided. If the holes are stripped, you might need to use longer screws or wood filler.

Unscrew the faceplate and strike plate. Then, remove the screws from the edge of the door to pull out the old latch.

Check alignment of the latch and strike plate. Adjust the strike plate position if needed.

Lubricate the lock mechanism with a light machine oil. Ensure the key is the correct type and not damaged.

Tighten all screws and ensure the latch is firmly seated in the door mortise.
