Dorwal patio door roller

A handy person from Johnson City, TN says:
Attached are photos of the Dorwal patio door roller that I need to replace. The steel roller is 1-1/4" dia. and is concave. The external metal bracket is extruded aluminum 2-1/4" x 1-1/8" with 15/16" locking tabs. I looked thru your pictures and cannot find the exact part, but your item # 81-005 looks like it might work.

Please advise.

I agree, our 81-005 looks similar. Acorn was known to use them for their Dorwal door, but they closed down. An exact match may not be available.
