All of our overhead storage products are designed to be the strongest and safest available, and that remains true with our 600 pound capacity overhead rack. This unit features a safety lip to prevent storage from sliding off of the rack, square steel tubing to provide strength, and a completely bolted together assembly for maximum durability. As with all of our overhead storage products, this rack features our innovative mounting track design that spans four ceiling joists for added strength and safety, and is also capable of being installed into any garage!
