SCREEN DOOR ROLLER
Hey there, thanks for writing in! I'm sorry to hear your purchase did not work out for you.
Your garage door roller more closely resembles our 87-214 Roller Assembly with Flat Brass Wheel. These are typically used for sliding windows, however, I believe this is the part you'll need for your replacement. Take a look over the dimensions for this hardware and compare it to your existing roller to determine if this is the right replacement for you.
