SWISCO - The Replacement Hardware Authority

M & W Door handle and mortise lock

A quick learner from USA says:
The door is early 1990s, sold by M&W Windows out of VA.

The lock, looking at it from the door edge: Wide 1/2"

Tall 3 3/16"

Mounting plate screws apart 3 11/16"

You will also see what appears to be a "Sc" on the side of the lock.

Thanks for posting! Start by looking at our 82-034 and 82-075. One of these may replace your handle set, depending on the thickness of your door. As for the mortise lock, see our 82-227 instead.
