The KNAACK 139-kl is a heavy-duty steel jobsite cabinet from the Jobmaster series, built for organized tool and material storage on active construction and trade job sites. The cabinet measures 60 inches tall, 60 inches wide, and 30 inches deep, delivering 59.4 cubic feet of total storage capacity. The 16-gauge powder-coated steel body resists impact and corrosion, while a proprietary recessed padlock system secures contents without an exposed hasp. Three full-length interior shelves handle longer items and keep gear sorted. A padlock is included. Installation and positioning are handled by tradespeople or site supervisors managing equipment logistics.
The 139-kl is suited for residential and commercial construction sites, industrial facilities, and service shops where centralized storage of tools, parts, and supplies is needed. The two-door configuration provides wide access to the full interior. The adjustable bottom shelf accommodates items of varying heights, while the fixed upper shelves provide consistent organization. Compatible casters (sold separately, model numbers 495, 505, and 516) can be added for mobility. The cabinet is also compatible with forklift transport, making repositioning practical on larger job sites.
Compatible with KNAACK caster model numbers 495, 505, and 516 (sold separately). Designed for use within the Jobmaster series jobsite storage system.
Positioning and setup is typically performed by site supervisors or general tradespeople. Ensure the cabinet is placed on a level, stable surface before loading shelves. When adding compatible casters, verify load capacity and lock casters before accessing the interior. Use a forklift only with properly rated equipment and follow applicable OSHA material-handling guidelines when relocating the unit on site.
