Patio door handle

Thanks for writing in! I believe your installation hole spacing could possibly be 4-15/16". With that said, your door looks like it can use the 82-080 Mortise Style Handle Set. The keyed version of this handle set is part 82-081.

To confirm that this is the right replacement, carefully look over the dimensions and design. See if this is the right fit for your door. You'll want to be especially sure that this handle will be compatible with your mortise lock. If you are not sure, please send a photo of your existing mortise lock and I'd be happy to take a look.
