Sliding glass door rollers

Thanks for posting, Glenn. At first glance this roller looks similar to either our 81-081 or 81-261. See the diagrams below. Compare the dimensions of your old roller and see if one of these match. Pay especially close attention to the width and height of the assembly, as well as the wheel diameter. Let me know if either of these rollers match yours, or if both differ, and if so, by how much.
