Looking to replace broken mortise lock

Question

I'm looking to replace a double hook mortise lock for a sliding Herulite glass patio door. The only marking it has says, "This end up." Do you have this part available? Thanks

Hello! Thanks for contacting us. I recommend our 82-238 mortise lock. This is specifically designed to work on handle sets like yours and I'm very confident it will work well in your door.

Also, just for future reference, Herculite is the name of the company who made your glass, but not your door. There may be another manufacturer name somewhere on the inside frame that may tell you who made it. This is just in case something breaks in the future, you'll know for sure what name to reference.
