Hello, most of the windows rollers in my house have fragmented due to age, but I could not find any useful information on them to figure out the replacement and, unfortunately, not in Home Depot either. I drew a graph attached and could you help me on identifying the replacement, please?

This looks like our 87-161 window roller. Compare your dimensions to our product page to see if it will work for you.

Hello Casey,

It looks the same. How do I install them? Just hammer in?

If you look at the ends of the roller, you will see a prong sticking out. To remove the old nylon wheel housing, you would stick a small screwdriver into the one end, forcing out the old wheel housing. By doing that, you will break off the prong, so you won't be able to re-use the roller.

To install a new 87-161 wheel housing just lightly tap in the new wheel housing until the prongs lock in.
