The K62 Rolling War Wagon combines chest and cabinet on heavy-duty casters for mobile site work.
Jobmaster portable chests
Jobmaster chests in 36", 42", 60" and 72" lengths are the portable storage solution for tradespeople — electricians, plumbers, service technicians and mechanical contractors needing a lockable tool kit that moves between sites. The 60" and 72" Jobmaster sizes carry complete tool kits and heavy equipment; the 36" and 42" sizes suit smaller kits and service vehicles.
Monster Box storage systems
Monster Box configurations include the cabinet type (pull-out drawers for organised hand tool and consumables storage), the chest type (maximum open-lid accessibility for site work) and the piano-lid type (lid open support arm and full-width access). Monster Box is Knaack's heavy-duty answer for sites requiring maximum security combined with high-volume storage.
Why Knaack
The American-engineered construction matters. Heavy-gauge steel walls, recessed lock systems that resist crowbar attack, weather-resistant gaskets and industrial casters — these are storage boxes designed for years of abuse on construction sites and mining operations where lesser products fail. Pair Knaack storage with proper site security procedures: lock to a fixed point, log box contents, and maintain key control.

People Also Ask — Knaack Job Site Storage
Q: What does Knaack make?
Knaack is an American-built industry standard for heavy-duty job site storage boxes, gang boxes, rolling work boxes, and field offices. Designed for construction, mining, and infrastructure sites where security and weatherproofing matter more than cosmetics. Made from heavy-gauge steel with multiple-lock systems, water-resistant seals, and reinforced corners. Knaack is the spec for major construction sites where theft and weather damage are constant risks.
Q: What's the difference between Knaack and consumer tool boxes?
Knaack uses heavier gauge steel (typically 1.6-2.0mm vs 0.8-1.2mm consumer), multi-point locking with internal lock bars (vs single-point locks), waterproof gasket seals, and reinforced corners. Consumer-grade tool boxes are designed for transport and home workshop; Knaack is designed to sit on a job site for years exposed to weather, attempts at theft, and rough handling. Cost difference reflects the construction grade.
Q: How are Knaack boxes secured against theft?
Multi-point lock bar engages multiple points around the lid. Recessed padlock pocket protects the lock body from attack. Tamper-resistant hinges. Many models accept multiple personal padlocks for shared-access control. For high-security sites, use additional chain-and-padlock through the bottom hooks, or bolt the box to a concrete pad. Knaack boxes have been the construction industry choice for decades — well-tested against site theft attempts.
Q: Can Knaack boxes be modified for tool organisation?
Knaack offers internal shelving, drawer systems, and divider accessories as factory options. After-market modifications (custom shelves, foam inserts) are common but check that they don't compromise the lid seal or lock engagement. For tool-specific organisation, foam shadowboard inserts give a clear at-a-glance view of missing tools — particularly useful on shared crews.
Q: What size Knaack should I buy?
Size to total tool volume plus 30-50% expansion room. Standard sizes: 16 cubic feet (medium tool box for individual tradesman), 24 cu.ft (full job site box), 36 cu.ft (gang box for crew tools), 60+ cu.ft (rolling work box for multi-trade site). Match to your needs and the available site space. For mining and remote sites, also consider rolling models that can be loaded onto trailers without forklift.
