Upgrade or replace worn closet door hardware with this top‑hung adjustable tandem roller assembly, engineered for smooth, quiet, and reliable bypass door operation. Designed to mount at the top center of the door, this assembly uses dual 1‑inch flat nylon rollers to evenly distribute weight, reducing friction and extending track life. A 5/16‑inch threaded steel adjustment rod allows for precise height alignment, making installation easier and ensuring doors glide straight and stay properly positioned. The stamped steel tandem housing delivers strength where it matters most, while the nylon rollers provide long‑lasting, low‑noise performance. Compatible with Prime‑Line top brackets N 6954 and N 6797, this adjustable roller fits closet doors from 3/4 inch to 1‑3/8 inch thick, making it an ideal solution for common residential bypass closet door systems.
