Rollers on sliding mirror doors - Jim

A handy person from Tampa, FL says:
The rollers are on the underside of the frame holding a large glass mirror and are approximately 35 years old. The hardware portion is intact but the rollers (plastic) and bearings are worn.

I removed the roller assembly from the exterior housing and found a number on it: D-719, stamped on the housing, not on the roller

Hi there! I've seen this roller a few times in the past. We've never been able to find an exact match, but our 81-125 is close. I'm just not sure how your exact dimensions compare to ours. Look them over and let me know if they differ, and how.

A handy person from Tampa, FL says:
The distance between the two clips on mine is 1 1/8th inches and there is probably a maximum of an additional 1/8th space available in the holes where the clips sit in the frame.

Hi there. I actually went to the warehouse and measured the distance between the two clips on the 81-125. I also measured 1-1/8". I agree with Tom's suggestion of going with our 81-1125 as a replacement.
