Knaack L.L.C. was the first to offer national distribution of jobsite storage boxes in Chicago, Detroit, Hammond, Cleveland, Hammond, Denver and Washington D.C. By 1968 Mr. Knaack moved the company to a 16,000 sq. ft. building in the current location. Along with the move came the purchase of the WEATHER GUARD® Truck Equipment brand from a small sheet metal company in St. Louis.
