The WEATHER GUARD Aluminum Lo-Side Box offers a powerful blend of security, sleek style, and everyday practicality—making it an exceptional upgrade for truck owners who want reliable storage without sacrificing bed space. Designed to mount along your truck’s bed rails, this compact vehicle storage solution keeps essential tools protected and within easy reach, all while maintaining full use of the truck bed for hauling larger items.
Equipped with the advanced 1KEY ULTRALOCK system, this model delivers next-level protection and convenience. The push-button, tamper-resistant lock provides quick access while ensuring your gear stays secure, and the one-key coding feature allows you to sync multiple boxes across a single vehicle or fleet. The reinforced lid opens a full 90 degrees for easy loading, and an optimized latching system reduces the force needed to close the box—perfect for busy workdays where efficiency matters.
Built for lasting performance, the heavy-duty welded aluminum construction delivers maximum strength without unnecessary weight. Its Gloss Black ARMOR TUF Powder Coat finish resists corrosion, scratches, and harsh weather—keeping your truck box looking sharp for years. A full weather seal protects tools and equipment from dust, moisture, and road grime, while welded gas strut shields, enhanced tie-down buckles, and PowerSync-compatible 12-volt access points add convenience and flexibility for worksite or everyday use.
