Andersen Gliding Door Tandem Roller Assembly for 8' Tall Doors (1982 to Present)
- Works with 200 Series Narroline, 200 Series Perma-Shield and 400 Series Frenchwood Gliding Patio Doors manufactured from 1982 to Present.
- Dual ball bearing rollers on bottom of the operating door panels provide smooth gliding operation with self-contained leveling adjusters.
- Do not use the regular tandem roller assembly for 8' tall doors.
- We recommend replacing both rollers at the same time.
