The set includes four steel rails (16 inches each), nine heavy-duty double hooks (7.8 inches), and mounting hardware. The hooks slide freely along the rails, allowing for flexible storage configurations. The rails can be used individually or connected together for a maximum total length of 64 inches. The system has a total weight capacity of 600 lbs and is suitable for storing items such as chairs, skis, strollers, bicycles, ladders, shovels, rakes, power tools, and gardening equipment. The hooks feature rubber-coated sleeves to prevent items from slipping. Installation requires a power drill and a level, and the rails must be mounted to wall studs. Weight: 20.37 lbs.
