Aluminum track is precision extruded to provide smooth
rail design provides single point hanger wheel contact for low roll
resistance, and dust traps on both sides of rails allow hangers to
operate freely when dust builds up.
Machine turned and balanced wheels offer low roll resistance,
feather touch operation. Hangers are height adjustable for precision
door alignment. Twin wheeled ball bearing hangers available for heavy
mount door guides effectively
hold door in place without binding and insure smooth door operation.
Johnson hardware is rigidly tested to meet ANSI standards.
