Patio Door Roller

Thanks for posting! Your patio door roller appears to be missing the outer housing. It will be important to double check the door for it and remove that piece from the door so that you can get an accurate comparison for the dimensions. There is a video tutorial tagged below to use as a reference.

For this style roller, we typically recommend either the 81-278 or the 81-279 Patio Roller Assemblies. The difference between the two of them is the diameter of the wheel.
