Thanks for posting! Your patio sliding door roller reminds me of our 81-158 steel, ball-bearing Dual Roller Assembly, with a 1-1/4" wheel diameter. Take a look over the dimensions and compare them to your existing roller to confirm that this is the right fit. I am confident this is the replacement you'll need. Alternate image for 81-158
