Maximise Storage Without Sacrificing Space
Running out of cab space? The Garvee 30-Inch Underbody Truck Box is the smart solution for reclaiming storage. Designed to mount securely underneath the chassis of trucks or on the A-frame of trailers, this rugged steel chest utilizes wasted space to keep your chains, jacks, and heavy tools organised, secure, and out of the way.
Why Choose Garvee?
Built for the Road
Constructed from reinforced heavy-duty steel with a powder-coated finish to withstand road salt, grime, and stone chips.
Dry and Secure
Features a rubber weather seal around the door to block out driving rain and road spray, keeping contents dry.
Easy Access
The drop-down door design provides full access to the interior, making it easy to load and unload heavy equipment.

Perfect for flatbed lorries, tippers, and utility trailers.
Professional Grade Security
Your tools are your livelihood. This box is equipped with a stainless steel T-handle latch that is easy to operate even with gloves on. The locking mechanism is drill-resistant and protected by a weather cap, ensuring your expensive gear remains safe from theft whether parked on-site or at a service station.

Heavy-duty chain stays prevent the door from dropping too far.
Engineered for Durability
The Garvee underbody box isn't just a metal box; it's a fortress. The 1.5mm thick steel walls are welded for superior strength. The door is supported by heavy-duty chains (or gas struts depending on model), allowing it to serve as a convenient shelf when open, perfect for placing tools while you work.
Details
- Space efficient. Designed for external mounting. It fits perfectly under the chassis of commercial vehicles or on the drawbar (A-frame) of trailers, freeing up your truck bed for larger cargo.
- Tough as nails. Made from robust carbon steel with a textured black powder coating. This finish not only looks sleek but provides essential protection against rust and corrosion from wet UK roads.
- All-weather protection. A continuous rubber seal lines the door frame. When the latch is tightened, it compresses the seal to create a watertight barrier, preventing water ingress even during motorway driving in the rain.
- Theft deterrent. The recessed stainless steel T-handle offers a secure 3-point or single-point locking system (model dependent). It sits flush to prevent snagging and includes a cover to keep dirt out of the keyhole.
- Ample storage. Dimensions: 30" L x 14" W x 16" H (approx. 76 x 35 x 40 cm). This size is ideal for storing tow straps, wheel chocks, battery jumpers, and general tool kits without adding excessive weight to your vehicle.
