Engineered to meet your heavy-duty, professional-level storage needs, this rack offers innovative details that aren't typically found on industrial shelving units. Dense wire grids prevent items from falling through, safety straps with weld nuts ensure easy assembly and top caps protect both you and your items from potential damage. The three adjustable metal wire shelves and one black laminated composite wood shelf can each support an evenly distributed 2,500 lbs., for a total load capacity of 10,000 lbs. Each shelf has two types of support straps in addition to the crossbeams to prevent them from buckling under pressure. Additional safety features include locking clips to secure the shelves into place and a mounting bracket that lets you attach your rack to a wall to eliminate the danger of accidental tipping. Glass-filled nylon feet safeguard the rack's finish against any storeroom moisture or liquid spills while preventing damage to floors.
