The Elite Series Mass Storage System is perfect for storing and organizing dumbbells, kettlebells, and slam balls in your home gym. It comes in 2-tier or 3-tier configurations with 42" or 70" shelves to suit your needs. Each shelf supports up to 1,000 LB, and the core units feature heavy-duty bolt-down uprights and side-bracing for durability and stability. It's easy to assemble with the included hardware and fully customizable with Elite Series add-ons like bumper plate shelves and weight plate holders. For increased capacity, this mass storage unit is double the length, combining two base model units of the same height and length to efficiently store and organize your equipment. CAUTION - Do not move your non-wheeled Mass Storage System without first unloading plates, dumbbells, kettlebells, and all other items. For best performance on non-wheeled Mass Storage Systems, we recommend bolting your unit to the floor.
