Heavy duty aluminum, metal, powder coated and diamond plate cross toolboxes and truck boxes for pickup trucks. Cross toolboxes can be mounted behind the cab of a pickup truck, and are designed for the professional contractor, individual or service person. The twin gull-wing lids "pop" open on these cross toolboxes with the aid of self-powered gas springs. Each cover operates and locks independently. Minimal space between the lids gives you that extra deep lid opening space for better cargo removal. These cross boxes for pickup trucks suspend from the top of the side rails (in the pickup truck bed) to provide plenty of room underneath for long materials that require the full length of the truck box. A handy tray lock prevents unwanted sliding of the interior tray when driving.
