ABSTRACT:
A simple, adjustable roller assembly for supporting sliding track doors and windows and comprising a U shaped bracket which journals a roller and includes a corner opposite from the journaled roller which engages the intersection between the stile and rail of a door frame. An adjusting screw passes through the stile or rail and engages the U shaped bracket whereby tightening of the screw pivots the bracket and roller into increasing downward movement by pivoting the bracket with respect to the inside corner defined by the junction of the stile and rail. In one alternate embodiment, a single screw adjusts a pair of side by side rollers journaled on a common shaft. In another embodiment the U shaped member includes a tap member extendable outward and securable at a spaced point on the door rail or sill. Tightening of this screw serves to bend the tab member and adjust the roller position. The bendable tab actually provides a degree of spring support for the door.
