I need to replace the rollers on my patio doors. My dimensions appear to be 11/16" wide with a 1 1/8" wheel. I see your 81-155 is the correct width but the wheel is 1 1/4" where as the 81-138 has a 1 1/8" wheel but the width is 3/4". Which one would you recommend?
I agree, the 81-155 looks like our best match. If the height and width are the same, then I think it can still work. You can turn the adjustment screw at the back of the roller to raise and lower the wheels. That should make up for the difference in wheel diameter. Let me know if you think that will work.
