Lock

Hello,

I would recommend starting by taking a look at the 82-214B mortise latch. Review the specifications below to see if this part matches up to the one you are looking for. Please note that our mortise uses a 45-degree keyway but yours may be at 90 degrees due to damage to the lock. Thanks for posting and let us know if you need anything else.
