sliding door roller

Your patio door roller looks a lot like our 81-258 Ador Hi-Lite Series 1200 Patio Door Assembly. Although, it appears to be missing the outer housing, which is likely still installed in the door frame. 

To determine if this will work as a suitable replacement, carefully look over the dimensions and compare them to your existing roller. This is the closest match we have to your existing roller.
