Wheel assembly for Kinco slider

Thanks for posting, Rob. Unfortunately, I cannot use this information to identify what roller you need. I can tell you that Kinco single glazed doors have used our 81-020, and Kingo dual glazed doors have used our 81-153, but I cannot guarantee that these are what you have. The only way to know would be to remove yours from the door and compare them to our specs. If neither match, you can take a few pictures and submit them here along with dimensions and I will try my best to find a better match.
