Dunnage shelves offer considerably more weight-bearing capacity than other Super Erecta Shelf shelves and can be combined with them to provide extra strength at the lower levels of a shelving unit where the heaviest loads will be placed. The 24”, 30” and 36" (914mm) length has a 1,600-pound (750kg) uniformly distributed static load capacity; the 48" (1219mm) shelves hold up to 1,300 pounds (600kg), and the 60" (1525mm) length holds up to 1,000 pounds (450kg). Removable wire deck fits over reinforced 1" (25mm) square, tubular frame. It lifts off for easy, thorough cleaning.
