Our Yukon 42 inch tool box is engineered for professionals and serious DIYers who demand maximum storage and durability. Constructed from heavy-gauge steel with reinforced corners and a powder-coated finish, this mid-size tool box offers the perfect balance of capacity and portability.
Whether you’re outfitting a work truck, organizing your garage workshop, or heading to a job site, the 42-inch platform provides ample room for power tools, hand tools, and accessories while fitting most full-size truck beds. We designed every detail—from the gas strut lift system to the weather-resistant rubber seals—to withstand years of demanding use.
Construction & capacity highlights

Steel Construction & Finish Details
We build the Yukon 42 inch tool box from heavy-gauge steel with a minimum thickness that exceeds industry standards for crossover-style truck boxes. The steel undergoes a multi-stage preparation process before we apply the powder-coated finish, ensuring exceptional adhesion and long-term corrosion resistance.
Reinforced corners use double-wall construction at critical stress points, while the lid features internal bracing to prevent warping under load. The black powder coating provides a professional appearance that matches most truck bed liners and accessories.

Storage Capacity & Interior Organization
Compartment Layout
The 42-inch width delivers 7.2 cubic feet of usable storage—enough for a full complement of power tools, hand tools, and job site essentials. Interior dimensions measure 39 inches wide by 16 inches deep by 14 inches tall, providing clearance for larger items like circular saws, drills, and toolkits.
We include a removable steel tray that spans the full width of the box, creating a dedicated space for small parts, drill bits, fasteners, and measuring tools. The tray lifts out completely for access to the main compartment below.
Weather Protection & Security Features
Weather-resistant rubber seals run the full perimeter of the lid, creating a barrier against rain, snow, and road spray. While no truck tool box is completely waterproof, our seal design significantly reduces moisture intrusion during transport and storage.
The dual paddle handles feature stainless steel construction that resists corrosion from road salt and chemicals. Each handle integrates a lock hasp compatible with standard padlocks, allowing you to secure valuable tools when parked.

Yukon 42 Inch Tool Box Questions
The exterior dimensions measure 42 inches wide, 18 inches deep, and 16 inches tall. The interior usable space measures 39 inches wide by 16 inches deep by 14 inches tall, providing 7.2 cubic feet of storage capacity.
The overall height includes the lid and mounting feet, so plan for approximately 16.5 inches of vertical clearance when considering tonneau cover compatibility.
The 42-inch width fits crossways in most full-size truck beds, including Ford F-150, Chevrolet Silverado 1500, Ram 1500, GMC Sierra, Toyota Tundra, and Nissan Titan models. It works best installed behind the cab in the front section of the bed.
For mid-size trucks like the Toyota Tacoma, Chevrolet Colorado, or Ford Ranger, we recommend checking your specific bed width, as some configurations may be too narrow for crossbed mounting. Consider our <a href=”/tool-boxes/”>smaller tool box models</a> if you need a more compact option.
The box features weather-resistant rubber seals that significantly reduce moisture intrusion, but like most truck tool boxes, it’s not completely waterproof or submersible. The seals protect against rain, snow, and road spray during normal driving and storage conditions.
For maximum protection, avoid pressure washing directly at the seal line, and periodically inspect the seals for debris that could prevent proper closure. The seal design keeps contents dry in typical outdoor use, but we don’t recommend storing moisture-sensitive electronics or documents without additional waterproof containers.
The dual paddle handles include integrated lock hasps that accept standard padlocks with shackle diameters up to 3/8 inch. We designed the system this way so you can choose your preferred lock type—keyed alike, combination, or high-security models.
The hasp openings are positioned to protect the lock shackle from bolt cutters when a quality padlock is installed. Stainless steel construction resists corrosion that could cause locks to seize over time.
Yes, installation is straightforward and typically takes 30-45 minutes with basic hand tools. The box includes pre-drilled mounting holes that align with standard truck bed mounting hardware.
You’ll need a socket set, drill, and appropriate mounting brackets or bolts for your specific truck bed configuration. We recommend using grade 8 bolts with lock washers for secure attachment. Detailed installation instructions are included with every unit.
The empty weight is approximately 68 pounds, making it manageable for two people to lift and position during installation. The heavy-gauge steel construction provides durability without being excessively heavy.
Once loaded with tools, total weight will vary based on your specific equipment. The reinforced lid and mounting system are engineered to support typical tool loads without flexing or warping.
The primary difference is storage capacity and truck bed compatibility. The 42-inch model offers 7.2 cubic feet of storage and fits most full-size truck beds with room to spare. The <a href=”/tool-boxes/yukon-46-inch-tool-box/”>46-inch model</a> provides 8.1 cubic feet and works best in trucks with wider beds or when you need maximum storage.
Both models share the same construction quality, weather sealing, and gas strut lift system. Choose based on your available bed space and storage requirements—the 42-inch is ideal if you want to preserve bed space for cargo alongside the tool box.
