Sashlock replacement
A sashlock replacement restores both the handle-operated latch and the separate locking bolt within one case.

Sashlock replacement — align both latch while deadbolt to the door preparation, with the installation method, protection and finishing details planned.
Confirm the required function, handle centres and door thickness. Both latch engagement and keyed locking should be checked after the agreed replacement.
