RKI Truck Bed Storage Boxes: Built for the Working Truck
When a truck is more than a daily driver — when it carries the tools, equipment, and livelihood of tradespeople, contractors, and fleet operators — the storage box bolted to its bed has to earn its place. RKI (Rawson-Koenig Inc.) has been building commercial-grade truck equipment since its roots as Koenig Iron Works in 1911, and their truck bed storage boxes reflect more than a century of refinement for real working conditions.
A Lineup Built Around How You Work
RKI doesn't offer a one-size-fits-all solution. Their truck box catalog spans several distinct product lines, each engineered for a specific mounting position and access style:
- Crossboxes — including the ST-Series double-lid crossbox, which features twin, gull-wing-style lids that operate independently, giving easy access from either side of the truck while mounting on the bed rail to preserve clearance underneath for additional storage.
- Side Boxes — mount along the side of the bed rail with spring-assist lid openings for convenient, one-handed access.
- Underbody Boxes (V-Series) — vertically hinged, heavy-duty steel boxes ideal for storing equipment below the bed or service body floor, available in multiple configurations and sizes.
- Topper Compartment Boxes — designed for flatbeds or service body tops, mountable on any flat surface with spring-assist lid openings.
- Floor Drawers — slide-out storage with a refined multi-stage striker and latching system for a cleaner front profile and a tighter seal.
Material Quality and Construction Details
RKI truck boxes are manufactured using minimum 14-gauge steel with stainless steel latches and hinges and come with a durable polyester powder coating finish offered in black or white. For those who prefer aluminum, aluminum RKI tool box units use glossy diamond-plate aluminum and are offered with gas shock lid arms, also featuring black or white powder coat finish.
One of RKI's standout engineering details is its sealing system. The upgraded automotive-style ribbed D-bulb seal provides greater resistance to water, dust, dirt, and other contaminants — made from closed-cell EPDM material that resists compression set, aging, UV, ozone, and oxidation, and can withstand temperatures above 300°F. This seal was specifically chosen to conform to the diamond pattern on RKI's tread plate aluminum boxes, and it comes installed as a standard feature across all truck boxes and floor drawers.
Designed and Built in the United States
Designed, engineered, and fabricated in the United States, RKI has built commercial truck equipment for fleets, municipalities, and contractors for more than four decades. Heavy-gauge steel and aluminum are specified for continuous commercial use, selected to withstand daily operation in demanding field environments, with standardized equipment designed for large-scale fleets, public works, and long-term vehicle programs.
RKI continues to offer some of the largest storage capacity tool boxes in the industry , and they stand by what they manufacture with one of the most comprehensive lifetime warranties available. For working professionals who depend on their truck storage every day, that combination of capacity, durability, and warranty coverage makes RKI a logical choice.
