Easily customize shelf height with the quick-adjust mechanism and locking clips, allowing 38 mm increments to accommodate items of all sizes. Built from Spcc carbon steel with a premium powder-coated finish, this 24 x 48 x 72 inch shelf resists rust, oxidation, and scratches while supporting up to 3000 lbs total.
