I have a glide assembly that is similar to your on line unit 87-219 but not exactly the same. Mine has the attachment hole on the opposite end and a nylon glide shelf on one side. Do you have a replacement for my unit?

I have seen these roller assemblies used on Premier windows. I am afraid this roller assembly is no longer available. Take a look at our 87-191 nylon roller. Perhaps this may be used as a replacement. Give it a closer look and get back to us with some thoughts.
