Help repairing handle
Hello,
I would recommend starting by comparing the 3-15/16" hole spacing of the 82-030 handle set to yours. This is a versatile replacement with an adjustable thumb latch. We'll include the images from our product page below. If the mortise lock inside the door needs to be replaced as well, we'll need to see yours with the door open. Thank you.
It looks like the installer flipped the entire handle so that the upward offset of the thumb latch would match the mortise lock. This isn't necessarily a problem but one benefit of the 82-030 is that it uses an adjustable thumb latch that can be mounted on the top, middle, or bottom of the handle plate. That way you won't have to worry about flipping the base to align with the mortise lock.
Also, I measured and included a photo of the measurements in mine. but I'm unsure it lines up with the 3 15/16"?
Thanks for your help
Unfortunately, we are not able to make out exact dimensions from photos but I agree with Casey that the 82-030 looks like a good replacement option as long as the hole spacing matches. I can tell you that 3-15/16" is a common size for these types of patio door handles.
You could also test the internal mortise lock using a slotted screwdriver in the space where the thumb latch would install. If you rotate it and the locking hooks do next extend properly, see the 82-265. We'll include the dimensions of this part below as well to confirm it's a match. Unforutnately, the handle sets and mortise locks are not available as a set since different combinations of handles and lock assemblies are used by various door manufacturers.
