TENNSCO Boltless Shelving: Add-On, Heavy-Duty, 48 in x 48 in, 84 in Overall Ht, 3 Shelves, Steel

Heavy-duty boltless metal shelving units generally are sturdier and can hold heavier items than light-duty and medium-duty shelving units. These shelving units have particleboard decking, which provides a smooth, solid surface that prevents items from falling through the shelving and will not mar or snag items placed on it. The decking installs over the shelving units' beams to distribute the weight of items placed on the decking across the beams.
