48 1/2" Black Aluminum Innerside Truck Box

JOBOX aluminum Innersides utilize the same Gear-Lock™ System, Self-Centering Latch Pin, RSL™ Lid and high-Strength Body Design as the Crossovers. They mount on the top of the bed side walls and are ideal for storing longer tools and equipment. Innersides help keep the bed free for storing bulky items. Combine Innersides with a Crossover to create a wrap-around storage system.


  • Tough Armor-Brite® powder paint finish has superior rust resistance
