This hi-side truck tool box provides 11.8 cubic feet of storage capacity for valuable tools, equipment, and parts, mounting along the bed rail to maximize accessibility while preserving your truck bed for supplies, materials, and larger equipment. Measuring 96.25" long, 13.25" wide, and 16" high, this extra-long configuration spans even longer than standard long-bed boxes, making it ideal for extra-long bed trucks or applications requiring maximum side-mounted storage length. At just 73 pounds, the aluminum diamond plate construction weighs significantly less than comparable steel boxes while providing excellent storage capacity and the distinctive diamond plate texture. The door opening (12.75" high by 45" wide) provides excellent access to contents, while the aluminum door and hinge provide complete corrosion resistance. The drill-resistant lock core and three-point latching system provide extreme security, while the rain gutter and full weather seal with memory-resistant D-shaped ribbed weather strip keep moisture out. The gloss black ARMOR TUF powder coat finish over aluminum diamond plate creates a sleek, modern appearance that coordinates perfectly with contemporary truck styling. Tool-less quick release doors adjust from 90 to 180 degrees with QuickClips, the removable parts bin keeps small items organized, and convenient attachment points secure materials and tools. For contractors, fleet managers, tradespeople, or anyone with extra-long bed trucks needing maximum-length side-mounted storage with lightweight aluminum construction and modern black diamond plate styling, this hi-side box delivers the comprehensive solution.
Extra-Long Lightweight Aluminum with Modern Black Finish
The defining advantage of this truck tool box is the combination of extra-long 96.25" length with lightweight aluminum diamond plate construction in a modern gloss black finish. At just 73 pounds, this aluminum box provides substantial 11.8 cubic foot capacity while weighing dramatically less than comparable steel boxes—delivering exceptional benefits for payload capacity, fuel economy, easier installation, and reduced stress on truck suspension.
The aluminum diamond plate construction provides professional strength while delivering exceptional weight efficiency. Aluminum offers natural corrosion resistance ensuring long-term durability even when constantly exposed to moisture, road salt, and harsh environmental conditions—the material maintains structural integrity through years of outdoor exposure without rusting or deteriorating. The diamond plate texture provides additional structural rigidity while creating the distinctive professional appearance that contractors and enthusiasts appreciate.
At 96.25" long, this is one of the longest hi-side truck tool boxes available, extending even beyond typical long-bed lengths to accommodate extra-long bed trucks or to provide maximum storage span on standard long-beds. This extra length is valuable for very long tools, extended-reach equipment, organizing tools by category across the substantial span, or simply maximizing the storage available along one side of your truck. The 13.25" width extends outward from the bed rail, providing adequate depth for tools and equipment. The 16" hi-side height creates 11.8 cubic feet of storage capacity—substantial volume for professional tool inventories.
The gloss black ARMOR TUF powder coat finish over aluminum diamond plate creates a sleek, modern appearance that sets this box apart from traditional bright aluminum. The gloss black finish offers distinct advantages: creates contemporary styling that coordinates with black truck accents and accessories, hides dirt and minor wear better than lighter colors, provides a custom appearance that enhances truck aesthetics, maintains the distinctive diamond plate texture visibility, and offers the sophisticated look that appeals to professionals who prioritize both function and style. The combination of lightweight corrosion-resistant aluminum with modern black styling creates premium equipment that performs exceptionally while looking sharp.
Professional Security and Weather Protection
The extra-long aluminum hi-side box is engineered with multiple security features working together to protect valuable tools and equipment across the extended 96.25" span. The drill-resistant lock core resists one of the most common break-in methods where thieves attempt to drill out locks. The three-point latching system provides extreme security by engaging locks at three separate points across the lid—distributing force and making prying entry extremely difficult even with the extra-long lid span and lightweight aluminum construction.
Security features can be configured as key-alike on request for fleet operations managing multiple vehicles with side boxes—allowing one key to access all units across your fleet for simplified key management.
The rain gutter and full weather seal keep moisture out of the high side truck bed tool box and your equipment. The memory-resistant D-shaped ribbed weather strip maintains its sealing effectiveness through thousands of opening and closing cycles and extreme temperature variations, ensuring your tool inventory remains dry and protected from rust and corrosion.
The aluminum door and hinge provide complete corrosion resistance throughout the box—there are no steel components that could rust over time. This all-aluminum construction is particularly valuable for trucks operated in harsh environments with salt exposure, coastal areas with salt air, or any conditions where corrosion is a concern. The combination of corrosion-resistant aluminum with the durable gloss black powder coat finish creates equipment that maintains both its functionality and appearance through years of professional use.
Professional Features and Modern Styling
The tool-less quick release doors adjust from 90 degrees to 180 degrees with QuickClips and no tools required. This adjustable door opening provides versatility: 90-degree opening for normal access in open areas, 180-degree opening (lid folds completely back) when you need maximum access to the interior or are working in tight spaces where a partially open lid would interfere.
The removable parts bin keeps small items organized within the 11.8 cubic foot storage space. Small parts, fasteners, fittings, and accessories can easily become lost in such a large box. The removable bin provides dedicated organization, and being removable means you can take it with you to the work area.
Convenient attachment points secure materials and tools in the pickup bed, providing tie-down capabilities that work in conjunction with the extra-long side box.
The door opening measures 12.75" high by 45" wide, providing excellent access to the interior along a substantial portion of the extra-long box length. This wide opening allows easy loading and retrieval of items, reaching across the interior, and organizing contents efficiently. The double lid construction with heavy-duty C-channel reinforced lids provides structural strength across the extra-long opening span even with lightweight aluminum construction.
The bed rail mounting location positions the box along the top of the bed rail, providing easy exterior access without consuming bed floor space. Installation takes approximately 0.7 hours (about 42 minutes) and involves securing the lightweight 73-pound box to your truck's bed rails—the manageable weight often allows one-person positioning where heavier boxes require assistance.
