When you need maximum secure storage that mounts on your truck bed rails while keeping the bed open for cargo, the Weather Guard Super Hi-Side Box (Model 291-3-02) delivers professional-grade performance with heavy-duty steel construction and a durable white finish. This super hi-side truck tool box provides 15.2 cubic feet of storage capacity for valuable tools, equipment, and parts, all while keeping your truck bed open for supplies and larger materials. Measuring 90.25" long, 16.25" wide, and 18" high, it offers exceptional storage volume that spans nearly the entire length of most long-bed trucks.
The door opening (14.75" high by 42" wide) provides wide, easy access to contents, while the aluminum doors and hinges reduce overall weight and resist corrosion. The three-point latching system and drill-resistant lock core ensure extreme security, while the rain gutter and full weather seal with memory-resistant D-shaped ribbed weather strip keep moisture out and your equipment protected. Finished with a Brite White ARMOR TUF powder coat, this box maintains its professional appearance and durability through years of demanding use.
Key Features
- 15.2 cu ft capacity for maximum side-mounted storage
- Three-point latching system with drill-resistant lock for extreme security
- Full weather seal and rain gutter protect tools from water and debris
- Heavy-duty welded steel construction with Brite White ARMOR TUF powder coat finish
Maximum-Capacity Hi-Side Design
The defining feature of the Model 291-3-02 is its expanded 15.2 cubic foot capacity, providing ample room for larger tools, power equipment, and supplies. Mounted high along the bed rails, this design keeps your truck bed floor open for hauling bulk materials, lumber, or other oversized cargo.
Hi-side truck tool boxes like this one position storage along the sides of the bed rather than across it, giving you quick, convenient access to tools and parts without climbing into the bed. The large, double-door opening allows wide visibility and easy reach to all interior contents. Using the QuickClips system, the doors can be adjusted from a 90-degree opening to a full 180 degrees without tools, offering versatile access depending on workspace or conditions.
The aluminum doors and hinges add strength while minimizing weight, reducing strain during operation and resisting corrosion over time. Together, these design elements make the Super Hi-Side Box ideal for professionals who demand a high-capacity storage solution that enhances both function and efficiency.
Professional Security and Weather Protection
Security and protection are cornerstones of the Weather Guard design philosophy. The three-point latching system secures the doors at multiple locations, distributing locking force evenly and providing strong resistance to prying or bending. The drill-resistant lock core protects against forced entry, ensuring your tools remain safe even in high-traffic or jobsite environments.
The integrated rain gutter channels water away from the lid and prevents pooling, while the full weather seal with D-shaped ribbed gasket creates a tight, long-lasting barrier against moisture and dust. The memory-resistant design maintains its shape through repeated opening and closing cycles and extreme temperature changes.
Combined, these features provide the ultimate protection against theft, weather, and wear—keeping your equipment dry, secure, and ready to use.
