Aluminum patio door at the watergate in DC

Hello,

Unfortunately, we were unable to locate your patio door roller assembly but we've found two possible replacements that are close to your dimensions. We carry the 81-030 with 1-1/4" wheels, as well as the 81-095 with 1-1/2" wheels. You would attach them from below the patio door rail with a screw. Take a look and see if one of these could work for your application. Thanks for posting.
