If you’re in construction or have ever been on a construction site, you’ve likely seen large, rugged, brown or green metal boxes near the work. Most likely those boxes are KNAACK boxes, which have been the highest standard since they came out in 1960. KNAACK is known for perpetually redesigning its products for user-friendliness and efficiency, making it an essential product for jobsite organization and tool security.
What Is a KNAACK Box?
A KNAACK box is a reliable, heavy-duty, weather-resistant tool and equipment storage solution designed and built for the jobsite. These boxes were specifically designed for security and mobility and come in a variety of sizes and configurations—from chest boxes and truck boxes to Safety Kages™ and huge storage cabinets. KNAACK prides itself on providing maximum security against theft “24/7” and touts its “no one has a better track record of proven protection”.
KNAACK products are great for:
- General contractors
- Electricians
- Plumbers
- HVAC techs
- Carpenters
- Field crews on mobile jobsites
- Anyone needing a product for maximum security of tools
What Makes KNAACK Different?
1. Durability
KNAACK boxes are produced utilizing heavy-gauge steel, designed to withstand years of abuse, neglect or adverse weather. They are known for their resistance to denting, warping, or corrosion.
2. Security
KNAACK was designed for security. Each KNAACK box comprises a three-point locking system, improved hinges and ball stud brackets.

Furthermore, the boxes encompass heavy-duty, 16-gauge steel body construction and fully arc-welded seams for added security in addition to separately locking compartments.
3. Weather Resistance
KNAACK boxes are built to handle whatever weather conditions are on site. Seam-welded seams and weather-resistant gaskets in addition to WEATHER GUARD® additions and accessories help keep moisture and dirt out.
4. Mobility
KNAACK boxes are ready for transport. Most boxes include caster-ready bases and crane-liftable designs for easy transport between jobs or on large job sites.
5. Power-Ready Design
Models with the PowerPass® Electrical Pass-Thru can run extension cords inside the box safely, enabling tool charging stations to remain secure, dry, and safe.
