walled aluminum track is precision extruded for smooth operation.
Keyhole mounting slots allow easy removal without tearing out walls. Box
design prevents rollers from jumping track. Convex 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
hanger design gives even weight distribution on track rails and will not
bind. Machine turned and balanced wheels offer low roll resistance,
feather touch operation. Hangers are height adjustable for precision
door alignment. Detachable hanger plate allows easy door installation or
jamb mount door guide effectively holds door in place without binding
and insures smooth door operation.
Johnson hardware is rigidly tested to meet ANSI standards.
