Wheel assembly for ASTR BEC OMCO sliding glass door

Hello, thanks for posting! We have several rollers that match the design of your assembly, but only one that comes close to your dimensions. I say "come close" because there are some slight differences that you'll have to double check.

The product in question is our 81-278. The outer housing is 1-3/8", like you described, but the outer housing width is 3/4", not 11/16". The roller is also 1-1/2" instead of 1-7/16".

These three dimensions are the most important. If they match, then the 81-278 will probably work well in your door. Please double check your measurements and let me know how they compare after another pass.
