JOBSITE TOUGH. ROAD READY.
Topsider toolboxes are designed to maximize storage and accessibility in commercial pick-up trucks by utilizing the space above the bed rails. The elevated design frees up the truck bed for larger cargo while maintaining a clean, professional workspace. If you need an open bed to haul large items or are looking to downsize from a service body, our topsiders can be combined with ladder racks, bed slides and accessories to give you the same capacity and functionality needed for the job without the extra costs.
