4' x 8' slider rollers

Question

Measure 3 1/8" long, 1 1/8" high, 3/4" wide at front, 5/8" at wheel pivot point, 1 1/8" diameter wheel. Looks like a 81-138?

Hello,

I agree that your roller resembles the 81-138 except that the housing is only 1" high as shown below.

We also offer the Acorn 81-030 roller that matches your housing dimensions but the wheel is a bit larger at 1-1/4". That may not be an issue since the height can be adjusted to make up for the difference. Review both options to determine the best ft for your door. Thank you.
