Need a replacement roller

A quick learner from Pittsburgh, PA says:

Can you help me find replacement rollers for my patio door! The dimensions are 3 1/2" long, 1 3/4" tall, and slightly over 3/4" thick. Probably closer to 13/16 of an inch thick.

Thanks for your help!

I'm afraid we do not have this complete roller assembly. I'm not sure if it's something we'll be able to provide. Could you just replace the wheel? If so, what is its diameter and thickness? We have the 81-237, which may work, but see what you think.

It looks similar to81-074 (1/8" shorter). At least worth a look. The rivet will probably be in the way, but it also is on Arcadia doors. I've never figured out why they put that type of rivet on these rollers. I always have to grind them off even with the edges.
