Thanks for your help.. Does the lock come with hardware handles etc? We need that as well.
No, the lock is sold by itself. Do you still have your old handles around? If so, I'd like to see them. If not, I will at least need to see the installation holes. I will also need to know the distance between the two outermost installation holes, center-to-center. Thanks!
I strongly believe they are really 3-15/16". This is a very popular hole spacing, while I've never actually heard of a glass patio door handle having a 4" hole spacing. Make sure to measure from the center of each hole, not their edges.
Great! Yes, it looks like you still have your keeper, so as long as the measurements match up I think you'll be okay with just these two parts.
The wood handle is meant to go inside the house. This is also the handle that holds the thumb lever in place. Let me know how it works out!
This is exactly the door my mom has. We ordered a different handle and lock (before we found the info on the door), and it is very hard to do. I think it may just not be the best fit. I may order both of the parts you mention. What is the "keeper"?
