Noncorrosive construction makes these boxes great for storing de-icing materials, but they can also be used for a variety of other bulk storage applications ... from PPE equipment to cleaning supplies. To safeguard contents, the lids can be secured with an extended-shank padlock (not included). Molded-in pockets on the base of 6, 12 and 18 cu. ft. models allow for easy relocation with a forklift.
