SINGLE BAR AND CHAIN STORAGE Enhance the functionality of your rack with our versatile storage solution, perfect for a 6-post setup or your 4-post rack. Create a dedicated space for storing a barbell accommodating both standard and specialty bars up to 2" in diameter. We also opted to create a dual purpose with this attachment. You can also store bands and chains (up to (4) per side) with a carabiner. What we were aiming to do was to utilize the dead space at the top of your rack this design seamlessly integrates with the corner gussets of your rack, offering a sleek, streamlined appearance. This storage system not only optimizes your training space but also maintains the professional aesthetics of your setup. Choose to color match your storage system with your rack at no additional cost when purchasing a rack, or opt for a custom color to make a bold statement and stand out. Build Quality As always, we strive to elevate every piece of equipment we manufacture, no matter the size. For this storage attachment, we machined two pieces of UHMW to provide 360-degree protection for your barbells and chains. Each piece of UHMW is recessed for a premium, high-end appearance that will make others envy your Irwin rack.
