Roller for Betterbuilt Windows

Question

This is a roller assembly on the bottom of a Betterbuitl window. There are 2 of them on each window. The assembly measures 1-3/4" by 3/4". It has 2 roller wheels and a plastic housing.

These windows were installed in 1995. I'm pretty sure the same rollers are on all of my windows regardless of size, and they are all pretty worn out. I'm interested in replacing them all.

This roller is similar to our 87-221, but it's admittedly hard to be sure so long as it's still installed. I recommend removing it from the window and comparing it to the photos and dimensions we show on the 87-221 store page. That should confirm for you whether or not this product can work.
