American Craftsman 50 Series Sliding Patio Door

Hey there,

The mortise lock you have here bears a very close resemblance to the 82-218 Mortise Lock. There are a few notable differences but I do not believe they should cause any issues with the installation.

Take a look at the diagram below and compare the dimensions to confirm it will be a fit. Be sure to take a look at the installation tagged below, if need. It provides a detailed explanation on how to install the lock.
