When you need secure tool storage along the full length of your truck bed without sacrificing cargo space, the WEATHER GUARD Hi-Side Tool Box (Model 372-5-02) delivers the perfect solution in an extended 72" configuration with sleek gloss black finish. This premium automotive accessory mounts on your truck's bed rails, keeping 8.9 cubic feet of storage accessible while leaving your entire bed floor open for lumber, equipment, materials, and cargo. The extended length is ideal for long-bed trucks or operators who want storage along the full bed length, providing quick access to tools anywhere along the truck side while maintaining the contemporary appearance that reflects professional quality. With rugged aluminum diamond plate construction, extra-wide door openings, and the innovative features that make WEATHER GUARD the professional's choice, this extended hi-side box in gloss black delivers the security, weather protection, and organizational capability that contractors, tradespeople, and serious truck owners demand—all wrapped in modern styling that complements today's trucks.
Extended 72" Length for Full-Bed Coverage
The 72.25" length of this hi-side box provides extended coverage along your truck bed rails—perfect for long-bed trucks or situations where you want tool access along the full length of the bed. This extended configuration offers several advantages: tools and equipment are accessible from more positions along the truck, the longer length provides better weight distribution, and you can organize items by location along the box for efficient workflow—keeping frequently used items near the tailgate and less-accessed items toward the cab.
At 13.25" wide and 16" high, the box provides 8.9 cubic feet of storage capacity while maintaining the fundamental hi-side advantage: your truck bed floor remains completely open. You can still haul full-length lumber, ladders, pipe, sheet goods, or any cargo requiring the full bed—the hi-side mounting on bed rails means storage doesn't compete with cargo space, making this ideal for contractors who need both substantial tool storage and regular material transport capability.
The extra-wide door openings—12.75" high by 33" wide on each side—are notably larger than standard hi-side boxes. The 33" width (compared to typical 29" doors) makes loading and accessing tools significantly easier, accommodating wider items and providing more comfortable reach into the box. This is particularly valuable with the extended length, ensuring you can efficiently access items stored anywhere along the 72" box without awkward reaching or repositioning.
Premium Aluminum with Professional Gloss Black Finish
The aluminum diamond plate construction delivers the ideal balance of strength, durability, and weight management for extended-length applications. At 65 pounds, the box remains manageable despite the 72" length—aluminum's light weight is crucial for extended configurations where steel would become prohibitively heavy. Aluminum naturally resists corrosion, ensuring reliable service without rust concerns even in harsh weather, road salt exposure, or chemical environments.
The Gloss Black ARMOR TUF powder coat finish over the aluminum diamond plate elevates the appearance while providing additional protection against scratches, chemicals, and UV exposure. This contemporary black finish creates a sleek, professional look that coordinates beautifully with black or dark-colored trucks, matches black bed liners and other black accessories for a unified appearance across your entire truck bed setup, and maintains its professional look even with the inevitable wear that occurs in working truck environments. For operators who understand that professional appearance impacts customer perception and business credibility—especially with the prominent visibility of a 72" hi-side box—the gloss black finish delivers both protection and sophisticated styling that enhances your truck's overall appearance.
The aluminum door and hinge system maintains durability while keeping weight down—important with the longer, wider doors required by this extended configuration. The heavy-duty welded construction and heavy-duty C-channel reinforced lids provide the structural integrity needed for the extended length, ensuring the box maintains its shape, sealing properties, and security throughout years of demanding commercial use.
Key Features
- Extended 72" Length: Full bed rail coverage provides 8.9 cu ft storage accessible along entire truck length
- Extra-Wide 33" Doors: Larger 12.75" H x 33" W openings for easier loading and access to stored items
- Tool-Less Adjustable Doors: QuickClips allow doors to adjust from 90° to 180° without tools for flexible access
- Professional Gloss Black Finish: Contemporary ARMOR TUF powder coat over aluminum diamond plate for durability and modern styling
Innovative Access and Organization Features
The tool-less adjustable door system using QuickClips provides exceptional versatility with the extended-length configuration. Adjust each door to 90° for standard access or 180° (flat against truck side) for maximum clearance when loading bulkier items or working in confined spaces. With doors along the full 72" length, this adjustability becomes even more valuable—you can configure doors independently based on which side you're accessing, what obstacles might be present, and whether you need maximum clearance or standard access at any given time.
The removable parts bin keeps small items, fasteners, bits, fittings, and frequently accessed parts organized rather than lost in the larger storage space. With 8.9 cubic feet distributed along 72", organization features like the parts bin become essential for maintaining efficiency and ensuring small items remain accessible despite the extended storage length.
The convenient attachment point integrated into the box design secures materials and tools in the pickup bed, adding cargo management capability beyond just tool storage. This creates a comprehensive bed organization system combining secure storage with cargo securing functionality—particularly valuable when hauling materials alongside your tools.
Security and Weather Protection
The drill-resistant lock core defeats common break-in attempts that target standard locks. The three-point latching system secures the lids at three locations—particularly important with the extended length where proper sealing and security across the full 72" requires multiple latch points to prevent prying attempts and maintain weather seal integrity along the entire length.
Weather protection uses WEATHER GUARD's comprehensive approach proven effective in extended configurations. The rain gutter channels water away from openings along the full length, preventing moisture intrusion even during or after rain. The memory-resistant D-shaped ribbed weather stripping maintains its sealing effectiveness through repeated use, temperature cycling, and UV exposure—ensuring the extended sealing surface remains effective at keeping tools dry and equipment protected regardless of weather conditions during transport or storage.
Installation and Quality
Installation on bed rails takes approximately 0.7 hours (about 40 minutes). Despite the extended 72" length, the bed rail mounting process follows the same proven method as shorter boxes, using included hardware and requiring only basic tools. The design is compatible with style-side truck beds—the most common configuration across truck manufacturers.
The Limited Lifetime Warranty demonstrates WEATHER GUARD's confidence in construction quality and materials even in extended-length configurations. USA manufacturing ensures the quality control standards, welding procedures, and construction methods that have made WEATHER GUARD the professional's choice for decades. Optional key-alike configuration is available on request for fleet applications or operators with multiple WEATHER GUARD products.
