Sliding glass door parts

Thanks for writing in. It's always difficult to identify replacements without knowing the old hardware, but in this case I think we can work it out. The hole spacing for the handle looks like it was 3-15/16". That's a good start because it narrows down the list of possible replacements considerably. 

The hole between the installation holes also appears to be centered. This means you need a handle set with a thumb latch that can be adjusted to be centered between the mounting holes. Something like the 82-035 or 82-069 would work for you. 

Finally, the mortise lock looks like it needs to be a double-hook style lock, and based on the way your frame is cut, as well as a keeper similar tot he 82-249, I believe you'd need possibly our 82-265 or maybe the 82-260. Look over both mortise locks and see if you think one might work for your door. 

Keep in mind these are all educated guesses, but it's the best we can do without seeing the original hardware. Let me know what you think.
