Slider Handle

A handy person from Mission Viejo, Rancho Santa Margarita says:
I'm looking to replace the handle on this slider. I can't find any information on the outside of the door that tells me the manufacturer. The pictures I've included aren't great but I believe it is? 3 15/16" on center for the screws. Please help. I need this soon.

This does appear to be a handle set with 3-15/16" hole spacing such as our 82-030. You can adapt the 82-030 outside pull to use our 82-310 Key Lock. This blog article here explains how. If you need a new mortise lock see our 82-239
