I am looking for replacement rollers for an Alenco sliding glass door since one roller has completely failed (roller fell off). The door handle assembly is a secondary concern since it still functions and could be replaced later. The broken roller assembly is shown in two of the uploaded pictures. It has the number "7867" stamped on it as well as the letters "NYC" and "A S". It measures 3/4" wide X 2-5/8" long X 1-3/8" tall. It is a single roller assembly.
Please let me know if this part is available. It may be best to replace both roller assemblies at the same time as your website suggests. I should also add that the existing roller wheel is 1-1/4" in diameter.
Thanks,
David
