tandem roller for Andersen vinyl slidin door

Thanks for writing in. There's a few different possibilities, and I can't narrow down exactly what you need based on the Andersen brand alone. That said, start by viewing our 81-018 or 81-128. Look them over and see what you think. If these don't match what you need, we'll need to see photos of your original roller out of the door, along with the width and height, and the diameter of the wheel. Many thanks.
