sliding door lock

Thanks for posting. The handle set looks like an older version of our 82-080 or keyed 82-081. Please compare. The original version of this mortise lock is unfortunately discontinued and not available. See the 82-268B. I am not sure if this will work for your door, but it's the closest replacement we have. Review the dimensions and see if you think it would fit. Let me know what you decide.
