In the fall of 1960, Howard Knaack began building jobsite storage tool boxes in a small, one-room shop in Crystal Lake, IL. Mr. Knaack's main outlet for these boxes was a tool supply distributor owned by his partners named Brock Tool Company.

Knaack L.L.C. was the first to offer national distribution of jobsite storage boxes in Chicago, Detroit, Hammond, Cleveland, 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.

In 1981, the WEATHER GUARD Facility added a powder coating system for WEATHER GUARD Product lines and became one of the first in its industry to offer the benefits of ARMOR-TUF® Powder Coating. Also in the early '80s, gas pistons were added to the WEATHER GUARD Truck Boxes, making them easier to open and close, therefore being safer to use than previous versions or competitors' models. Van equipment was added in 1984.

KNAACK® Jobsite and Tool Storage Products have achieved strong growth and industry leadership, and have not stopped introducing new products, like the Steel Underbeds, redesigned Aluminum and Steel Truck Box line, new Sliding Ladder Rack and the 2006 NTEA Work Truck Show Award-Winning Low-Profile Aluminum Truck Box.
