Sliding glass door

It's very difficult to say what you need without seeing the original hardware, as this varies quite a bit even when you have manufacturing information. The hole pattern makes me think this door might have used our 82-218 Mortise Lock, but I can't be certain. Look over the dimensions and let me know what you think. This kind of lock is compatible with a handle set like our 82-030, but it's entirely possible that you might have to drill new holes to use this handle set, even if the 82-218 seems correct. I can't guarantee any of this will work, but it's the best I can do without seeing the old hardware. Look over these parts and let me know what you think.
