The WEATHER GUARD Gloss Black Lo-Side Box delivers rugged durability, convenient access, and top-tier security for truck owners who need dependable storage without giving up valuable bed space. Designed to mount along the bed rails, this low-profile box provides easy side access to tools and equipment while allowing the rest of the truck bed to stay fully open for hauling lumber, gear, or oversized cargo. Built from heavy-duty welded steel and engineered with professional-grade locking and weather-proofing systems, it’s a standout choice for contractors, tradespeople, and everyday truck owners looking to upgrade their vehicle storage solution.
This model features the latest 1KEY ULTRALOCK system—a major advancement in secure truck box technology. With detent technology that gives you quick visual confirmation when the box is fully locked, plus the ability to program multiple boxes to a single key, it offers unmatched convenience and peace of mind. The tamper-resistant push-button lock is engineered to protect against prying and break-ins, making it one of the strongest, most reliable locking systems in the automotive accessories market.
A full weather seal shields your equipment from rain, dust, and debris, ensuring your tools stay dry and protected year-round. The lid opens a full 90 degrees for easy access, whether you're grabbing gear at the jobsite or organizing items in your driveway. Inside and out, the box is built for maximum durability—heavy-duty C-channel reinforcements, welded gas-strut shields, and an automotive dual-stage rotary latch deliver long-lasting performance. The Gloss Black ARMOR TUF Powder Coat finish not only looks sharp but also resists rust, corrosion, and fading. Enhanced tie-down buckles give you extra flexibility for securing external cargo, and the PowerSync-compatible 12-volt access port allows for simple electrical upfits like lighting or powered accessories.
