Searching for One and a quarter inch slide door tandem wheelers

Hello, thank you for posting,

The closest we carry to your style is the 81-087, but it has a 1-1/2" wheel size. If all other dimensions match up to your original, you can consider switching out the wheel with the 81-266 roller and axle kit if you find that the 1-1/2" does not fit correctly for your door.

If the original housing is still in good shape, we do carry the 81-241 1-1/4" stainless steel wheel along with the 81-130 axle kit. Take a look and let me know what you think!
