ABSTRACT:
A supporting roller assembly for a sliding door has a downwardly spring loaded guide track engaging roller supported for vertical floating movement by a mounting bracket containing a limited stop plunger which is spring loaded downwardly against the roller carrier. The bracket is slotted and carries a clamp screw accessible from the side of the door for clamping the bracket firmly about the plunger to secure the plunger in a fixed position for limiting upward movement of the guide roller against the action of its spring.
