When you need the absolute maximum secure storage that mounts on your truck bed rails, the WEATHER GUARD Super Hi-Side Tool Box (Model 297-3-02) delivers professional-grade performance with jumbo capacity and heavy-duty steel construction. This jumbo super high side truck tool box provides an exceptional 21.4 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, 16.25" wide, and 24" high, this is the ultimate side-mounted truck tool box—combining extra-long length with jumbo 24" height to create the largest storage capacity available in steel side-mounted configuration. The door opening (20.25" high by 42.75" wide) provides exceptional access to contents, while the aluminum door and hinge reduce truck tool box weight and protect against corrosion. 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. At 174 pounds, the 14-gauge steel body construction with bright white ARMOR TUF powder coat finish ensures maximum durability for years of demanding professional use. 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 the absolute maximum side-mounted steel storage capacity with professional security, this jumbo super hi-side box delivers the ultimate solution.
Jumbo 21.4 Cu Ft: Maximum Side-Mounted Capacity
The defining feature of this truck tool box is the jumbo 21.4 cubic feet storage capacity created by combining extra-long 96.25" length with super high side 24" height. This represents the ultimate in side-mounted truck tool box capacity—approximately 80% more storage than standard 16" high boxes and nearly double the capacity of many competitor models.
The 24" jumbo height provides exceptional vertical storage—50% taller than standard 16" hi-side boxes and 33% taller than 18" super hi-side boxes. This extra height accommodates taller equipment, allows stacking items vertically for better space utilization, provides room for larger power tools and equipment, and simply offers more organizational options for extensive professional inventories. The 20.25" door opening height (compared to typical 12-15" openings) allows easy loading and retrieval of larger items without struggling to fit equipment through restrictive openings.
Combined with the 96.25" extra-long length—extending even beyond typical long-bed trucks—and the 16.25" width, this box creates a massive 21.4 cubic feet of organized storage. To put this in perspective, that's enough capacity for comprehensive tool sets spanning multiple trades, extensive parts inventories, large equipment collections, or simply everything a busy professional operation accumulates over years of business growth.
The 14-gauge steel body is even heavier than the 16-gauge used in standard boxes—this is the thickest steel in the WEATHER GUARD steel box lineup, providing enhanced security, greater dent resistance, and maximum structural integrity necessary to support such massive capacity. At 174 pounds, the substantial weight reflects the heavy-gauge construction and jumbo dimensions, ensuring the box stays firmly mounted despite the extensive storage capacity.
Extra-Long 96.25" with Jumbo 24" Height
The combination of extra-long 96.25" length with jumbo 24" height creates storage proportions specifically designed for maximum capacity in side-mounted configuration. The 96.25" length accommodates extra-long bed trucks or provides maximum span on standard long-beds, ensuring you're utilizing the full available length along your truck's bed rail.
The jumbo 24" height is particularly valuable for operations with diverse equipment sizes. While standard and super hi-side boxes work well for hand tools and typical equipment, the jumbo 24" height accommodates: large power tools like circular saws, reciprocating saws, or grinders that don't fit in shorter boxes, stacked tool cases or organized layers of equipment, taller specialized equipment or testing instruments, bulk quantities of materials or consumables, or comprehensive inventories that require substantial vertical organization.
The heavy-duty C-channel reinforced double lid provides structural strength across both the extra-long 96.25" span and the jumbo 24" height opening. This reinforcement prevents warping or sagging despite the massive lid dimensions and ensures the lid maintains proper operation and weather sealing through years of use.
The heavy-duty welded construction creates a rigid structure across the jumbo dimensions—critical for a box this large that must withstand constant vibration, loading, and unloading while maintaining structural integrity. The 14-gauge steel and welded construction ensure the box doesn't flex, warp, or develop the structural issues that thinner materials or lighter construction might experience in such large dimensions.
Maximum Security and Professional Features
The jumbo super hi-side box is engineered with security features appropriate for protecting the substantial tool investment that 21.4 cubic feet typically represents. The drill-resistant lock core resists drilling attacks, while the three-point latching system provides extreme security across the extra-long, jumbo-height lid span. The 14-gauge steel body provides maximum theft deterrence—this is the heaviest steel available, resisting prying, cutting, and forced entry attempts better than thinner alternatives.
Security features can be configured as key-alike on request for fleet operations.
The rain gutter and full weather seal keep moisture out despite the massive door opening dimensions. The memory-resistant D-shaped ribbed weather strip maintains sealing effectiveness around the entire perimeter, ensuring your extensive tool inventory remains protected from rust and corrosion.
The aluminum door and hinge reduce weight while protecting against corrosion—particularly important in such large dimensions where steel door components would add excessive weight. The tool-less quick release doors adjust from 90 to 180 degrees with QuickClips, providing versatility for accessing the deep interior. The removable parts bin keeps small items organized within the massive storage volume.
The bright white ARMOR TUF powder coat finish over 14-gauge steel provides protection and professional appearance. The bed rail mounting with approximately 0.7-hour installation secures the substantial 174-pound unit across the extended length.
The Limited Lifetime Warranty and USA manufacturing reflect quality standards for the ultimate capacity steel side-mounted truck tool box.
