Need a lock.

Hello,

It's tough to be sure but your mortise lock is a similar style to the 82-218 or 82-223. Note that the 82-218 has a 45-degree keyway, while the 82-223 keyway sits at 90 degrees with the lock engaged. Review the specifications below to determine if one of them could work for your repair. Thank you!
