Built for Uncompromising Durability and Security
The 1702505 is engineered with a hybrid material construction that offers the best of both worlds: strength and corrosion resistance. The box body is forged from rugged 14-gauge carbon steel, robotically welded for exceptional strength and rigidity to withstand road vibration and potential impacts. This robust steel body is then finished with a gloss black powder coat, providing a tough barrier against rust, scratches, and chemical exposure. The drop-down door is crafted from lightweight, rust-proof smooth aluminum, reducing overall weight without sacrificing durability. Security is paramount, which is why this box features a die-cast locking T-handle latch that ensures your contents stay secure. A built-in automotive-grade bulb seal lines the opening, creating a watertight and airtight seal that locks out moisture, dust, and road grime, keeping your tools clean and dry in any weather.
