A-LG4 Low Profile Cross Boxes are Heavy Duty, High Capacity, Built Tough with Smooth or Diamond Bright-Tread Plate Aluminum Finish and offer easy access from either side of the Truck.
The Twin Gull-Wing Lids pop open with the aid of self-powered Gas Springs. Each Lid operates and locks independently. Minimal space between the lids gives you that extra deep Lid opening space for better cargo removal. Two keys are provided.
The Cross Boxes suspend from the top of the side rails to provide plenty of room underneath for long materials that require the full length of the Truck Box.
Comes Standard with Mounting Kit (M3500R)
Cross Boxes can be used separately or in combination with our High Capacity Side Mount Boxes.
