About this mortise lock

Features
- 1" - 1-3/4" thick doors
- Bright brass finish
- Interior and Exterior knob included.

Questions and answers
Does it include a cylinder?
Many mortise locks ship without a cylinder so it can be keyed to your system. Check the specifications on this page, and we can supply a matching cylinder or core.
Will it fit my door?
Mortise locks need a mortise-prepped door with the right backset and faceplate size. Match the series and backset, or send us measurements.
