Top Mount Tool Box

Top Mount Truck Tool Boxes for Contractors & Fleet Pickup Trucks

Keep your tools secure, organized, and within reach with a heavy-duty top mount truck tool box built for daily job site demands. Pro Fleet Upfitters carries and installs professional-grade top mount tool boxes for contractors, tradespeople, and fleet operators who need reliable, weatherproof tool storage that sits along the bed rails and keeps the cargo floor open for materials and equipment.

The Most Popular Truck Tool Box Style for a Reason

Top mount tool boxes — also known as crossover tool boxes — are the go-to choice for contractors and fleet trucks. They span the width of the bed just behind the cab, providing deep, accessible storage for hand tools, power tools, and supplies while leaving the majority of your truck bed free for hauling.

Benefits of Top Mount Truck Tool Boxes

  • Deep, Accessible Storage – Full-open lids provide easy access to tools and equipment from either side of the truck
  • Bed Floor Stays Open – Sits along the bed rails behind the cab, keeping the cargo floor clear for large materials and loads
  • Secure Locking Lid – Heavy-duty locking systems protect tools from theft and unauthorized access on the job site
  • Weather Resistant – Sealed lids and durable finishes keep contents protected from rain, dust, and UV exposure
