Door is a heavy aluminum door, I believe by MI.
Length (as shown in photo): 2-1/4"width (widest point): 9/16"Height (casing only): 1-1/8"Wheel diameter: 1", concave roller
Marked with "Ultra" brand. I gather from searching that they are not made anymore.

It's possible it is a 1-1/8" diameter wheel. It's difficult to measure.

Hi there!

Thanks for reaching out to us. Take a look at the 81-044 roller. We recommend you review the specifications and compare them with yours to see what you think.

This roller has a 1" diameter wheel, but we also have the 81-223 1-1/8" wheel and 81-310 axle kit.
