Rollers for sliding Anderson patio door

Thanks for posting. Andersen sliding doors often use either the 81-018 or 81-149, but there's no way of knowing which, or either of these rollers, you need without removing the old ones and comparing. When you do this, compare with the dimensions below and see if either of these options match what you need.
