Sliding glass Patio Door -AcornDorwal

The piece you're showing here is just the inside portion of a complete roller assembly. There should be an outer housing in the door still. In order to ID a good match, I need to see the whole thing together; specifically, I need to see it from the back end, top, and side. Let me know if you can get those photos for me.

Thank you so much for these photos. This roller looks very much like our 81-027. I think this may be what you want, but it's admittedly hard to make out your exact dimensions. Look this product over and let me know what you think.
