The Edsal 77" W x 72" H x 24" D Metal Shelving Unit is a standing 3-shelf storage rack with welded steel frames, welded steel beams and wire shelves to support a capacity of 2000 lbs. per shelf. This unit has steel braces on both end frames for added strength and capacity. The three 72" wire shelves are adjustable in 3" increments to accommodate items of different heights and have middle tie bars to eliminate rotation of beams under heavy loads. The beams on this storage rack feature beam end clip tabs that secure to the end frame post slots. This aids in quickness of assembly and ease of adjusting each shelf. This storage rack meets NSF standards for food equipment. Use the add-on Rack and Shelf Kit (sold separately) for extra storage options.
