Patio door handle set
I'm afraid that we don't sell anything that matches those specifications. Before I say anything for sure I'd like to see photos of the handle set itself. At the very least I may recognize it and can point you in the right direction.
Thanks! This handle set looks very similar to our 82-087. I think this is exactly what you were looking for, but review this product and let me know if you had any questions.
I would have to see a clearer picture of your mortise in order to make a recommendation. I can just about make it out in your first photo, and if I'm looking at what I think I'm looking at, then you can use our 82-227 as a replacement.
A clearer photo would allow me to give you a more confident recommendation. At the end of the day, photos are always the best method of identification. Dimensions are helpful but by themselves they do not indicate design or function, which are equally as important.
Thanks! I'm very confident that the 82-227 is the mortise you want. However, feel free to ask any questions you may have about this product and I will do my best to answer.
