Glass patio door handle

A home owner from Eastlake, OH says:
No markings or numbers written in hardware.

We just need a new lock, not a whole set; if possible.

Thanks for posting! Your mortise lock looks a lot like our 82-238. Compare its dimensions to your current hardware and let us know what you think.

I think you might be right! I might've misspoke though. I need a new keyhole lock. The current key we have won't work for it anymore.

Please see our 82-310 for a new key lock. If you want an entire keyed handle set you can check out the 82-081. If you have any further questions just let us know!
