Tough and spacious, the Karrite Voyager roof cargo box is a perfect accessory for those who require more space for storage than their vehicle can offer. The Voyager consists of high-density polyethylene, a lengthy-lasting material that stacks up to bumps, rocks, and then any other obstacle a road can offer. This versatile box can be mounted directly on the roof, or on existing roof-racks (via u-bolts). The box's 18 cu-ft of space provides you with lots of room for added luggage and sports gear. One hundred pound load capacity. Measures 46" by 38" by 18" high . Used, but in good condition.
