Patio door replacement roller

Thanks for posting. I believe you might have our 81-006. The width seems to be 3/4", and the height of the assembly just over 1/2", which would be close to the 81-006's height of 5/8". In comparison, another similar roller, the 81-288, has a slightly 'lower' height of 13/32". See the images below for reference. Still, pictures of measuring tape are not always accurate to go off of, so I'd do your best to double and triple-check these measurements to confirm the 81-006 matches what you need. Let us know you find.
