Sliding glass door roll

Hello,

Unfortunately, we could not locate a match to the patio door roller shown in your photos, though I have a few suggestions. If your roller housing is in good working order, you might be able to just replace the wheel. Take a look at the 81-266 roller kit, which comes with a 1-1/4" wheel, as well as the 81-272 kit with the 1-1/2" larger wheel. 

We've also related three rollers on this page, 81-023, 81-278, and 81-279. These have different roller housing dimensions and different diameter wheels than yours. Though it may be possible, installing these types of rollers can be a bit of a job. You would need to remove the bottom rail of the door off of the glass door lite. Then you would need to drill a "countersink" hole to install the 33-103 flat head screw. That screw would go into the top of the housing to secure the roller in place. I'd recommend starting by looking over the 81-023 diagram below. Thank you.
