If you’re looking for a dependable, secure, and smartly designed vehicle storage solution, the WEATHER GUARD Steel Lo-Side Box in White is built to meet the demands of hardworking professionals and everyday truck owners alike. Designed to mount along your truck’s bed rails without occupying valuable cargo space, this rugged 4.0 cu ft box provides fast, easy access to essential tools and gear—all while delivering top-tier protection against theft and harsh weather.
Constructed from heavy-duty welded steel and finished in a crisp, durable White ARMOR TUF Powder Coat, this lo-side box is engineered for long-term performance. The reinforced lid structure, memory-resistant weather strip, and advanced latching system work together to shield your equipment from dust, water intrusion, and daily wear. At the heart of the box is WEATHER GUARD’s latest 1KEY Ultralock system, which provides powerful break-in resistance and allows all WEATHER GUARD boxes in your setup or fleet to be keyed alike. The tamper-resistant push-button lock offers clear visual confirmation that your gear is safely secured—no guesswork required.
Practical features enhance daily usability, including a smooth 90° lid opening, improved latch ergonomics, and integrated 12-volt access for lighting or other upgrades. Enhanced tie-down buckles make it easier to secure oversized or multiple cargo straps, and the box’s low-profile design maintains excellent rear visibility. Whether you rely on your truck for demanding jobsite work or weekend projects, this lo-side box keeps your tools organized, protected, and ready for action.
