When you need extra-wide secure storage that spans the full width of your truck bed with the revolutionary 1KEY ULTRALOCK system, the WEATHER GUARD Saddle Box Extra Wide delivers professional-grade security in durable steel construction with bright white finish. This extra-wide steel truck toolbox (Model 116-3-04) provides 15.5 cubic feet of storage capacity while maintaining an 18.5" height profile that accommodates substantial tool inventories. Measuring 72" long, 27.5" wide, and 18.5" high, this full-width saddle box mounts over the wheel wells in your truck bed, providing organized tool storage while leaving the center bed floor open for cargo. The new 1KEY ULTRALOCK combines superior break-in protection with one key simplicity, allowing one key to work across all your boxes—whether multiple boxes on a single truck or an entire fleet. The tamper-resistant push button lock with detent technology provides quick visual assurance your gear is locked down and protected. At 163 pounds, the 5-piece welded steel construction with 18-gauge body provides maximum durability and security while the bright white ARMOR TUF powder coat finish ensures years of dependable service. The full weather seal protects against the elements, while the 90° cover opening, optimized latching system requiring less closing force, 12-volt access for electrical upfits, and enhanced tie-down buckles demonstrate thoughtful engineering. With USA manufacturing and Limited Lifetime Warranty, this extra-wide steel saddle box represents the next advancement in truck box security combined with substantial storage capacity.
Revolutionary 1KEY ULTRALOCK System
The defining innovation of this truck toolbox is the new 1KEY ULTRALOCK from WEATHER GUARD that combines superior break-in protection with one key simplicity, allowing one key to work across all your boxes. For contractors, fleet managers, or anyone operating multiple trucks or boxes, the traditional approach of managing dozens of different keys is inefficient, frustrating, and creates security vulnerabilities when keys are lost or misplaced.
The 1KEY ULTRALOCK system features a tamper-resistant push button lock that can code multiple boxes on a truck or an entire fleet to the same key. This means you can have saddle boxes, side-mount boxes, crossover boxes, and other WEATHER GUARD storage all keyed alike—one key unlocks everything. For fleet operations, this extends across all vehicles, simplifying key management dramatically and reducing costs when keys need replacement.
The push button lock mechanism is more tamper-resistant than traditional key cylinders—it's designed to resist the picking, drilling, and forced entry attempts that thieves commonly use. The detent technology provides quick visual and tactile assurance that your gear is locked down and protected—you can see and feel when the lock is properly engaged, eliminating the uncertainty of whether you actually locked your box.
The combination of superior security with simplified key management represents a fundamental advancement in truck box design. The system maintains the extreme security that professionals require while eliminating the key management headaches that have plagued multi-box and fleet operations for decades.
Extra-Wide Steel Construction for Maximum Security
The extra-wide 27.5" depth creates 15.5 cubic feet of storage capacity—substantially more than standard saddle boxes. This additional width accommodates larger tools, equipment, and more extensive inventories. The 72" length spans the full width of most truck beds, while the 18.5" height provides excellent vertical capacity for comprehensive tool storage.
The steel construction with 18-gauge body provides the ultimate in security and durability. Steel offers advantages that aluminum cannot match: superior resistance to prying and forced entry attempts, greater impact resistance preventing dents from accidental contact or deliberate damage, enhanced theft deterrence through material strength and weight, and maximum structural integrity supporting heavy tool loads.
At 163 pounds, the substantial weight reflects the heavy-gauge steel construction and large dimensions. This weight ensures the box stays firmly mounted, provides significant theft deterrence (thieves cannot simply lift and carry the entire box), and demonstrates the robust construction necessary for professional daily use with extensive tool inventories.
The 5-piece welded construction creates a rigid structure more durable than bolted or riveted designs. The heavy-duty C-channel reinforced lid prevents warping or flexing across the 72" span, while the C-channel reinforced front panel adds structural integrity. The welded gas strut shield protects the lid support mechanism.
The saddle box configuration mounts over the wheel wells, providing full-width storage while leaving the center bed floor completely open for cargo. This design is ideal for operations that need organized tool storage without sacrificing the ability to haul materials, equipment, or supplies requiring bed floor space.
Advanced Features and Professional Construction
The optimized latching system requires less force to close for easier use—a thoughtful improvement that makes daily operation more convenient, particularly when closing the lid with cold hands, wearing gloves, or working quickly. The automotive dual-stage rotary latch mechanism provides secure closure with smooth operation.
The 12-volt access for electrical upfits enables installation of interior lighting, charging systems, or other electrical accessories inside the toolbox. This PowerSync compatibility allows you to power equipment or charge batteries without running external wires or compromising weather sealing.
The enhanced tie-down buckles offer larger clearance for universal or multiple straps, providing secure attachment points for additional cargo or equipment stored on top of the toolbox when needed.
The full weather seal with memory-resistant D-shaped ribbed weather strip protects against the elements, keeping tools dry and preventing rust even in harsh conditions. The weather seal is particularly important for steel toolboxes where moisture protection prevents corrosion of both the box and the tools stored inside.
The 90° cover opening allows the lid to open to vertical position for unobstructed access—the single lid provides full access to the 15.5 cubic feet of interior space without requiring excessive clearance behind the truck.
The bright white ARMOR TUF powder coat finish over steel provides protection against scratches, chips, and corrosion while creating a clean, professional appearance. The white finish maintains brightness, coordinates with white trucks popular in commercial fleets, and shows cleanliness and professional organization.
The in-bed mounting location secures the box over the wheel wells, with installation taking approximately 0.3 hours (about 18 minutes).
The USA manufacturing and Limited Lifetime Warranty demonstrate WEATHER GUARD's confidence in construction quality for demanding professional applications.
