The IRON AMERICAN Alpha Double Barbell Storage 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 2.5 inch and 5/16-inch heavy-duty lag anchor screws with stainless steel washers make installation super easy and allow countless items to be hung 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. Furthermore, the screw holes have plenty of clearance from the bottom of the rack, so it's easy to drill into the wall. As with all of our products, IRON AMERICAN backs your purchase with 24/7 support and a lifetime warranty, both of which you'll be hard-pressed to find anywhere else.
