When you need secure, accessible tool storage without sacrificing truck bed space, the WEATHER GUARD Hi-Side Tool Box (Model 364-5-02) delivers the perfect solution with a sleek gloss black finish. This premium automotive accessory mounts directly on your truck's bed rails, positioning storage up and out of the way while keeping your entire bed floor open for lumber, equipment, materials, and cargo. With 7.9 cubic feet of storage capacity in a rugged aluminum diamond plate construction featuring a contemporary gloss black powder coat finish, this high-side truck tool box provides the security, weather protection, and organizational features that professional contractors, tradespeople, and truck owners demand—all wrapped in modern styling that complements today's trucks. The innovative design combines quick-access dual lids, adjustable door positioning, extreme security features, and comprehensive weather sealing in a lightweight aluminum package that won't corrode or add excessive weight.
Hi-Side Design: Maximum Storage, Maximum Bed Space
The hi-side configuration represents one of the smartest approaches to truck bed storage for operators who need both secure tool storage and full use of their bed floor. Unlike crossover toolboxes that consume valuable bed space or limit cargo length, this hi-side box mounts along the bed rails, utilizing vertical space above the bed rather than occupying the floor area itself. This means you can still haul full sheets of plywood, long lumber, ladders, pipe, equipment, or any other cargo that requires the full bed length—while maintaining quick access to your most frequently used tools, parts, and equipment.
At approximately 64.25" long, 13.25" wide, and 16" high, the box provides substantial 7.9 cubic foot storage capacity without intruding into your cargo area. The design is particularly valuable for contractors who need to transport both materials and tools on every job—framers carrying lumber and hand tools, electricians hauling conduit and testing equipment, plumbers transporting pipe and repair parts, or landscapers moving equipment and maintenance supplies. You get the organizational benefits and security of a dedicated toolbox without the cargo capacity compromises that come with other storage solutions.
Premium Aluminum Diamond Plate with Gloss Black Finish
The aluminum diamond plate construction delivers the ideal combination of strength, durability, and weight savings for truck bed applications. Aluminum naturally resists corrosion—no rust issues even in harsh weather, exposure to moisture, road salt, or chemical environments. The diamond plate texture provides excellent slip resistance when accessing items and adds structural rigidity to the panels while creating the classic appearance that's been the hallmark of quality truck accessories.
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, and maintains its professional look even with the inevitable wear that occurs in working truck environments. For operators who take pride in their equipment and understand that professional appearance impacts customer perception, the gloss black finish delivers both protection and sophisticated styling.
The aluminum door and hinge system further reduces weight while maintaining strength and durability. At a lightweight construction, this hi-side box won't significantly impact your truck's payload capacity or fuel economy—yet it's built tough enough for demanding commercial use. The heavy-duty welded construction and heavy-duty C-channel reinforced lid provide the structural integrity needed to withstand vibration, impacts, and daily use that characterize professional truck operations.
Key Features
- Hi-Side Bed Rail Design: Mounts on bed rails to provide 7.9 cu ft storage while keeping entire truck bed floor open for cargo
- Tool-Less Adjustable Doors: QuickClips allow quick release doors to adjust from 90° to 180° without tools for flexible access
- Extreme Security: Drill-resistant lock core with three-point latching system provides maximum protection against break-ins
- Professional Gloss Black Finish: Contemporary ARMOR TUF powder coat over aluminum diamond plate for durability and modern styling
Innovative Access and Organization Features
The double lid opening design provides excellent access to stored items, with each door measuring 12.75" high by 29" wide—large enough to accommodate most tools, equipment, and parts while maintaining structural integrity. What truly sets this hi-side box apart is the tool-less adjustable door system using QuickClips. Without any tools required, you can adjust each door to open at 90° (perpendicular to the truck) for standard access, or at 180° (lying flat against the truck side) for maximum clearance when you need unrestricted access or are working in tight spaces.
This adjustability is transformative in real-world use. In your garage or tight parking situations, the 90° position prevents doors from hitting walls or adjacent vehicles. At job sites where you're parked close to buildings or equipment, you can configure doors for the available space. When you need maximum access to load or unload larger items, the 180° position gets the doors completely out of your way. The QuickClip system makes these adjustments fast and tool-free—just release, adjust, and secure in seconds.
The top-mounted removable parts bin adds valuable organization capability. This separate bin keeps small items, fasteners, fittings, or frequently accessed parts organized and easy to find rather than loose in the bottom of the box. The removable design means you can take the entire bin with you to the work area when needed.
Security and Weather Protection
Security is paramount when your livelihood depends on the tools stored in your truck. The drill-resistant lock core defeats common break-in attempts that target standard locks. The three-point latching system secures the lid at three locations rather than just one central point, making prying attempts exponentially more difficult and ensuring the lid remains secure even under force.
Weather protection is equally comprehensive. The rain gutter channels water away from the opening, preventing moisture intrusion when opening the box even during or after rain. The full weather seal uses memory-resistant D-shaped ribbed weather stripping that maintains its shape and sealing effectiveness through years of repeated openings, temperature cycling, and UV exposure. This complete weather sealing system keeps tools dry, prevents rust on steel tools, protects electronics and testing equipment, and ensures that moisture-sensitive materials remain in good condition.
Installation and Quality Assurance
Installation on bed rails takes approximately 0.7 hours (about 40 minutes) with basic tools. The bed rail mounting method creates a secure attachment that won't shift or loosen over time. The design is compatible with style-side truck beds—the most common bed configuration across truck manufacturers.
The Limited Lifetime Warranty demonstrates WEATHER GUARD's confidence in construction quality and materials. USA manufacturing ensures quality control standards that have made WEATHER GUARD the trusted choice for professionals. Optional key-alike configuration is available on request for fleet applications or operators with multiple WEATHER GUARD products.
