Hello there. This looks a bit like our 81-033. Compare the dimensions and let me know if anything differs.

Honestly I believe I have 1 5/32" for a height. Given the fit of this roller in the door I suppose that extra 1/32" matters. Your thoughts or comments?

The height of the housing differing can pose an issue for installation into the frame. Unfortunately this size is the best we can supply.
We cannot guarantee it will fit correctly. If the housing is able to be reused, another option to consider would be switching out the wheel using the 81-266 roller and axle kit. Let us know if you have any additional quesitons.
