Sliding glass door locking handle
Thanks for posting. Hm, this is a little unusual. Your existing Handle Set looks like it might be something like our 82-087. This has a hole spacing of 3-15/16". However, the hole spacing on your missing handle set looks like it has a hole spacing of 4-15/16" instead. Now, it looks like your mortise latch is missing for this door as well, is that correct? Take a look at our 82-239 Multi-Point Mortise Lock for a replacement. Here's the catch: this mortise lock is specifically for 3-15/16" Handle Sets! I assume this might have been a custom door, which could explain all these contradictions in design. Long story short, you will need to drill new holes to install your new handle set; but this way you can order a handle set that matches your existing set. See our 82-087.
