Side Dump Truck Boxes

Side Dump Truck Boxes

Versatile to meet the job

The Demco Truck Mount Box Kit provides side dump capabilities for many different situations. The shorter size enables access to smaller areas and tighter job sites. With the largest capacity per foot, the rounded vee dump body allows for larger loads and quicker unloading. The Side Dump Truck Boxes are fully functional side dumps that can be mounted to a tractor or a truck chassis. On standard tractors, bolt-on subframes allow for over 5th wheel mounting and multiple uses with the same frame. The FlexCorner® design and large G-rail eliminates corner cracking and is lighter and stronger than two rail systems. The dump body and materials are built with the same proven reliability as our Demco Side Dump Trailers.
