Rollers for a sliding glass metal door

I couldn't find a match for this but I do have an idea. Now, I'm not sure about the other dimensions on your roller, but take a look at the 81-023 to see if this will work for you. I have used this type in patio doors where the original roller was no longer available. I can't guarantee it will work for you, all I can say is that it will depend entirely on your dimensions and how it installs. 

We also have the 81-083 roller. This roller is held into the frame using the screw tab which would line up with the assembly screw that holds your door together. 

If you find that you are not sure on either of these products then you should consider just replacing the wheel by itself. See our 81-266 roller and axle kit.
