KNAACK: The Most Trusted Name in Jobsite Security

When it comes to protecting tools and equipment on the worksite, few names carry the weight of KNAACK. Founded by Howard Knaack and his partners in a small shop in Crystal Lake, Illinois in the fall of 1960, the company was built to fill a growing demand for "ready-made" jobsite storage boxes. What started as a modest local operation quickly grew into a nationally recognized brand. National demand for KNAACK toolboxes drove expansion to a manufacturing facility of over 400,000 square feet employing nearly 500 team members.

Built on a rich heritage of experience and innovation, KNAACK has established a reputation as the world's most trusted name in jobsite security. That reputation wasn't built overnight — it came from a relentless commitment to engineering improvements that raised the bar for the entire industry. The company pioneered industry firsts like TGIC Polyester Powder Coating and the addition of gas pistons for safety, among other innovations. What hasn't changed in six decades is the KNAACK legendary tan — a color chosen to help hide dirt from jobsites like other colors can't.

Built for the Jobsite, Designed to Last

At the heart of the KNAACK lineup are its iconic shop tool boxes — heavy-duty storage chests engineered to withstand the demands of professional contractors day in and day out. These chests are equipped with the WATCHMAN® IV Lock System and recessed handles for added security and ease of transport. Whether protecting power tools overnight or organizing supplies on an active site, a KNAACK box delivers around-the-clock peace of mind.

For contractors who need mobility alongside security, KNAACK's utility carts bring that same level of protection to rolling workstations. The Cart Armour™ system is an interlocking steel paneling solution that encapsulates mobile work carts to secure them and their contents from theft. With oversized, 8-inch diameter rubber wheels and both swivel and locking features, the KNAACK Armored Transport maximizes mobility even when pushing or pulling maximum payloads across the jobsite.

Beyond toolboxes and carts, KNAACK also offers versatile storage containers that bring the same jobsite-grade security to a wider range of storage needs. Well beyond traditional tool storage and security, KNAACK's innovation takes jobsite protection to the next level.

Vehicle-Mounted Solutions for the Working Professional

KNAACK's expertise extends beyond the jobsite floor and onto commercial vehicles. Their ladder racks and roof racks are engineered to keep equipment secure during transport. The Weather Guard Quick Clamp and Nissan NV ladder rack units are designed for roof mounting on commercial vans and minivans. The Quick Clamp Ladder Rack includes modified mounting plates, front rails, a beefed-up clamp mechanism, and a tougher exterior case. These vehicle-mounted systems are a natural extension of KNAACK's broader mission: keeping professional tools safe, organized, and ready to work.
