Ultimate Super Hi-Side Configuration for Maximum Storage
The defining feature of this truck tool box is the ultimate super hi-side configuration that combines maximum length with super height to create the largest side-mounted storage capacity available. At 90.25" long and 18" high, this box provides an impressive 15.2 cubic feet of storage capacity—approximately 35-40% more than standard hi-side boxes and the ultimate solution for professionals with extensive tool inventories.
The super hi-side design extends to 18" high compared to standard side boxes at 12-14" or regular hi-side boxes at 16". This additional height creates substantially more vertical storage space, accommodating taller equipment, stacked tool cases, larger power tools, or simply more of everything professional operations require. Combined with the 90.25" length that spans nearly the entire length of long-bed trucks, this creates an exceptional storage volume that can handle the most demanding tool and equipment requirements.
Hi-side truck tool boxes mount on the bed rails of your truck, positioning storage along the side of the bed rather than across it. This side-mounting approach offers several strategic advantages: it provides quick access to valuable tools, equipment, and parts from outside the truck bed without climbing in, keeps the truck bed open for supplies and materials that wouldn't fit in enclosed storage, allows you to organize extensive tool inventories systematically along the substantial length, and maintains the ability to load full-length materials along the truck bed floor without interference.
The 90.25" length is specifically valuable for long-bed truck owners (typically 8' beds) who want to maximize side-mounted storage. The 16.25" width extends outward from the bed rail, providing substantial depth for larger items and stacked storage. The super hi-side 18" height creates maximum vertical capacity while still fitting under most truck caps with adequate clearance.
The door opening measures 14.75" high by 42" wide, providing excellent access to the interior along a substantial portion of the box length. This large opening allows easy loading and retrieval of even bulky items, reaching across the interior, and organizing the extensive 15.2 cubic feet of contents efficiently. The double lid construction with heavy-duty C-channel reinforced lids provides structural strength across the long opening span.
Professional Security and Weather Protection
The super hi-side box is engineered with multiple security features working together to protect the substantial investment in tools and equipment that 15.2 cubic feet typically contains. 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 on the pickup truck tool box provides extreme security by engaging locks at three separate points across the lid—distributing force and making prying entry extremely difficult even with the long lid span.
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 and reduced replacement costs.
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 extensive tool inventory remains dry and protected from rust and corrosion even when the truck is exposed to rain, snow, washing, or harsh conditions.
The aluminum door and hinge reduce truck tool box weight while protecting against corrosion. Aluminum naturally resists rust, ensuring these high-wear components maintain their operation and appearance through years of exposure to moisture and road conditions. The weight savings from aluminum doors and hinges helps offset the substantial steel body weight of this maximum-capacity box, making installation more manageable while preserving truck payload capacity.
Professional Features and Versatility
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, 180-degree opening (lid folds completely back) when you need maximum access to the extensive interior or are working in tight spaces. The ability to adjust without tools means you can change the configuration quickly.
The removable parts bin keeps small items organized within the substantial 15.2 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 for these items, 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 maximum-length side box. These attachment points ensure you can still secure cargo in your truck bed even with the extensive side box installed.
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 substantial box to your truck's bed rails using appropriate mounting hardware along the extended 90.25" length.
Heavy-Duty Steel Construction
The ultimate-capacity super hi-side box is constructed from heavy-duty steel with heavy-duty welded construction, providing the maximum durability necessary for professional daily use with extensive tool loads. At 151 pounds, the steel construction ensures the box stays firmly mounted across its substantial dimensions, provides significant theft deterrence through weight and strength, and delivers the structural integrity to withstand years of demanding use.
The heavy-duty C-channel reinforced lid construction provides strength across the long double lid span, preventing warping or flexing even when items are placed on the super hi-side top or when the lids experience stress. The C-channel reinforcement creates rigidity across the 90.25" length and 18" height.
The bright white ARMOR TUF powder coat finish ensures years of dependability while creating a clean, professional appearance. This commercial-grade coating resists scratches, chips, rust, and corrosion, maintaining structural integrity and appearance through years of exposure. White maintains professional image, coordinates with white trucks, shows cleanliness, and reflects heat.
The Limited Lifetime Warranty demonstrates WEATHER GUARD's confidence in construction quality for demanding ultimate-capacity applications. USA manufacturing ensures quality standards for truck tool boxes supporting extensive professional inventories.
