Peachtree Citadel Sliding Door
Thanks for posting. I can't be sure what might work for you without seeing the original hardware. That said, in past discussions for customers with Peachtree sliding doors we have opted for them to look at the 82-005 Surface Mount Sliding Door Handle Set. This has a hole spacing of 4-15/16"; you'll want to look over all the dimensions to see if this could work for you. If you want to adapt an outside key lock to this handle set, you can use our 82-306. Look over both parts and let us know if you think this could work for you. If none of this seems right, provide pictures of either the original handle set, or if not available, the holes in the sliding door where these parts can be mounted. Many thanks.
