A quick learner from Champlain, NY & Canada says:
There are 2 rollers at the bottom of the door.
Metal (now rusted) and metal wheels.

The wheel itself is 1.25 inches diameter.
If you need all of the other measurements please advise.

Good afternoon! I'm having trouble finding this exact roller. Could you give me a few more dimensions? I'd like to know the width and height of the housing. Thanks!
A quick learner says:
The width of the thickest part (not including the rivet) is 9/16" and the height is approx 1 5/16"

Thank you for your patience in this matter. We were unable to find an exact match, but check out our 81-268. Could this possibly work as a substitute? I'm not sure. Check it out and let me know what you think.

Just replaced a similar roller with the 81-268 Swisco unit. It fir perfectly
