Rivetwell Boltless Shelving with Wire Deck from Hallowell offers sturdy storage space for all of your materials. The boltless, steel frame snaps together quickly and makes it easy to add extra shelves later. Double-rivet beams ensure the shelves won't wobble or tip. The wire deck allows air to circulate freely and reduces dust buildup. Create a row of shelving by attaching adder units to a starter unit. Adder units have only one front post and won’t stand alone, so you’ll need to order a starter unit for each row of shelving. Choose from many sizes.
