Help identifying roller part

Hi,

I believe the replacement part I'm looking for is most likely your 81-250, but I want to confirm before ordering them. The images don't have a plastic roller part around the bearings since this is the part that broke off. When measuring another roller, I think the diameter was closer to 3.25cm which might be closer to the 81-271. If it's not able to be identified, do you have a recommendation which one would work (my guess is the 81-271)?

Thanks.

I believe your wheel is closer to our 1-1/4" diameter wheel, once centimeters are converted to to inches. The 1-1/2" of the 81-271 might be too large for your door. I think the closer roller would be the 23-043. Ultimately, though, it's your call!
