Metal roller for sliding patio door

Thanks for posting. The most critical dimensions in identifying patio door rollers is the width and height of the outer housing, as well as the diameter of the wheel. If your old assembly's width is 3/4" but its height is 1-3/8", I suggest you take a look at either our 82-278 1-1/2" Roller Assembly or our 82-279 1-1/4" Roller Assembly. The only difference between these two rollers is the diameter of the wheel, so compare that dimension with the wheel on your old roller to see what matches best. Let us know what you think.
