Outrigger. 1" square chrome tube. The 1" square tube chrome outrigger has universal 1/2" slots on 1" center. Use brackets, round or rectangular tubing, or shelving (sold separately) to complete your setup. Includes floor leveler. The outrigger is unique because unlike wall standards, weight is transferred to the floor, not the wall, so heavier loads can be stocked on the outrigger versus ordinary wall standards. 84"H. The outrigger is priced and sold per single upright.
