If you need a compact, secure, and professional-grade vehicle storage solution that maximizes your truck’s bed space without sacrificing accessibility, the WEATHER GUARD Steel Lo-Side Box in Gloss Black is engineered to deliver. This 4.0 cu ft lo-side box sits neatly on your bed rails, giving you quick reach to tools and gear while keeping the center of your truck bed open for lumber, equipment, cargo, or recreational gear. Perfect for contractors, tradespeople, fleet users, and truck enthusiasts, it blends high-strength steel construction with advanced security and long-term durability.
Built with heavy-duty welded steel and finished in a tough Gloss Black ARMOR TUF Powder Coat, this box is designed to withstand years of jobsite abuse, weather exposure, and daily wear. The reinforced lid and welded gas strut shield add extra rigidity and protection, while the full-perimeter weather seal ensures dust, moisture, and debris stay out. At the center of its security performance is the WEATHER GUARD 1KEY Ultralock system—a powerful, tamper-resistant lock that can be matched across multiple boxes for fleet-wide convenience. A simple push-button lock mechanism provides visual confirmation when the box is fully secured, giving you confidence your tools are safe.
The thoughtful design continues with a smooth 90° lid opening, ergonomic latching that requires less force to close, enhanced tie-down buckles for managing multiple straps, and integrated 12-volt access for PowerSync lighting or electrical accessories. It’s a smart choice for anyone needing a dependable, low-profile toolbox that enhances truck storage without compromising style, security, or ease of use.
