The IRON Alpha 2 Olympic Barbell Storage Wall Mount Rack is an essential low-cost and must-have product for all gyms small or big. We tested durability strength and functionality to determine the right design for all conditions. The 2 inch heavy-duty black oxide screws 2 drywall anchors and black oxide washers make installation super easy and allow countless gym accessories to be hanged and stored in drywall (into a stud) or concrete (1/4-inch drill bit required to do so). Unlike other racks our barbell rack is strategically made a bit deeper so there is extra room for larger diameter bars chains and resistance bands. In addition we added custom hanging slots for hanging lifting chains or travel bottle liquid chalk clips. As with all of our products IRON backs your purchase with 24/7 support and a lifetime warranty both of which you ll be hard-pressed to find anywhere else.
