Side‑mount toolboxes give you easy, arm‑level access to tools while keeping your truck bed fully open. Built tough for contractors and commercial work trucks.

Side‑mount (top sider) toolboxes are the ideal storage upgrade for contractors and work trucks that need fast, organized access to tools without climbing into the bed. Mounted along the top of the bed rails, these boxes free up the entire bed floor while giving you secure, weather‑tight storage right at arm’s reach.

We offer a full selection of top sider toolboxes built from heavy‑duty aluminum or steel, engineered for daily job‑site use. Choose from single‑door or double‑door designs, full‑length compartments, adjustable shelves, and reinforced doors that open outward for easy access. Weather‑resistant seals, stainless hardware, and durable powder‑coat or diamond‑plate finishes ensure long‑lasting performance in any environment.

Side‑mount toolboxes are perfect for electricians, plumbers, HVAC techs, welders, and fleet operators who need organized storage for hand tools, fittings, hardware, PPE, and job‑site essentials. Pair them with an underbody box or crossover box to build a complete work‑ready storage system tailored to your truck and trade.

If you want maximum storage without losing bed space, top sider toolboxes deliver unmatched convenience and durability.
