Lost hardware for double sliding door

Thanks for posting. The mortise lock looks like the 82-218, which works with a variety of keepers, including the 89-020 and 89-021. This mortise lock type works with handle sets that have 3-15/16" hole spacing. See our 82-030 for such an example. I am afraid we do not sell 'dummy' handle sets, i.e., handle sets that you would attach to the door that has no mortise lock in it. I suppose you could retrofit an 82-030 to do this job. Take a look at these parts and let us know what you think.
