Key Features
- Spacious 20.0 Cubic Feet Capacity: Designed to store large, heavy-duty tools and gear securely under your truck bed
- Heavy-Duty Aluminum Construction: Lightweight yet rugged aluminum diamond plate resists corrosion and reduces overall vehicle weight

The WeatherGuard Model 662-0-02 Under Bed Box is the ultimate solution for professionals who need dependable, protected storage on the road or job site. Constructed from heavy-duty welded aluminum, this jumbo underbed truck box offers 20 cubic feet of capacity, making it ideal for securing oversized tools, chains, straps, and gear that might not fit inside traditional truck boxes. The diamond plate aluminum body provides exceptional strength while keeping the overall weight light, ensuring better fuel efficiency and easier handling compared to steel alternatives.
Durability and protection are built into every detail. The Clear ARMOR TUF Powder Coat finish adds a tough, corrosion-resistant layer that withstands road salt, chemicals, and daily wear, keeping the box looking and performing like new for years. The heavy-duty C-channel reinforced door is fitted with a full-length rain gutter and a memory-resistant D-shaped weather seal, providing a barrier against moisture, dust, and debris. Whether you’re driving through rain, snow, or mud, your tools and equipment stay dry, clean, and secure.
For convenience and ease of use, the stainless steel D-handles are ergonomically designed to provide a firm grip—even while wearing gloves—and they create a tight, weatherproof seal when closed. The rotary-style, two-position latch system and three-point latching mechanism enhance security by ensuring multiple locking points along the door’s frame. The QuickClips system allows the door to be released without tools, letting you adjust the opening angle from 90° to 180° to suit your workspace—perfect for tight spaces or full-open access on job sites.
Engineered for demanding work environments, this under bed truck tool box installs easily on flatbeds, platform trucks, and dump bodies using standard mounting brackets (hardware sold separately). Despite its heavy-duty performance, the aluminum build keeps the unit lightweight at 94 lbs, ensuring your truck maintains balance and efficiency.
Every WeatherGuard box is backed by a Limited Lifetime Warranty, a testament to the brand’s commitment to lasting quality, security, and dependability.
