Side Mount Truck Box

Side Mount Truck Tool Boxes for Contractors & Fleet Pickup Trucks

Maximize your truck bed storage without sacrificing cargo space with a professional-grade side mount truck tool box built for daily job site use. Pro Fleet Upfitters carries and installs durable side mount tool boxes for contractors, tradespeople, and fleet operators who need secure, organized tool storage that keeps the center of the bed completely open for materials and equipment.

Store More. Haul More. Work Smarter.

Unlike crossover or chest boxes that span the full width of your bed, side mount tool boxes install along the inner bed rails — giving you lockable tool storage on both sides while keeping the entire bed floor free for lumber, pipe, equipment, and large loads. It's the ideal solution for contractors who need both organized tool access and maximum hauling capacity.

Benefits of Side Mount Truck Tool Boxes

  • Full Bed Access – Mounts along the bed sides so your entire cargo floor stays open for large materials and equipment
  • Secure Locking Storage – Heavy-duty locking lids keep tools protected from theft and weather on and off the job site
  • Easy Curbside Access – Low-profile design allows quick access to tools without climbing into the bed
  • Weather Resistant – Sealed lids and durable finishes protect contents from rain, dust, and UV exposure
  • Heavy-Duty Construction – Built from aluminum or steel for long-lasting durability under demanding work conditions
  • Pairs Well with Other Upfits – Works seamlessly alongside ladder racks, headache racks, and bed organizers
