This vertical barbell storage holder fits seamlessly 2x2 inch and 3x3 inch power rack uprights. Equipped with practical 2-in-1 spacer washers, it adapts 1-inch holes to 5/8-inch size, and matched M14 bolts perfectly suit standard 5/8-inch holes, achieving wide compatibility with most common squat racks and power cages. Crafted from premium stainless steel, this sturdy bracket features outstanding rust-proof performance and solid load-bearing capacity, serving well in home garage gyms, commercial fitness centers and humid use environments for long-lasting service.
