Searching for Arcadia 900-21292

A quick learner says:
I am looking to replace at least two sets of Arcadia sliding glass door handles 900-21292 installed in 1962. These are black. The distance between the two screws on inside handke is 5 1/2 inches. Many thanks!!

Hello,

It looks like you have an old and discontinued Arcadia 800 Series patio door. This hardware isn't made anymore, but I believe that you can use our 82-218 mortise lock with either our 82-020 or 82-033 handle set. Unfortunately, you will need to drill new holes for either of these two handle sets with 3-15/16" hole spacing since we do not offer anything with 5-1/2" spacing. Take a look and see what you think.
