This is a 22x56 folding polypropylene cargo carrier, this lightweight cargo carrier easily folds out of the way. With its lightweight design and solid support it actually assembles relatively easily and fits any 2 inch receiver hitch. This cargo carrier is a combination of steel and polypropylene. The steel frame gives it 500 pounds of carrying capacity while the polypropylene tray helps keep everything light. There is some assembly required but it is easy to do with sockets and wrenches. As you can see, the cargo carrier itself has plenty of holes and slots to give your tie downs plenty of room to grip. What is really nice about this carrier is that it also folds up. When you are not using it, why have it hang out? You can easily fold it up against your vehicle, go down the road, and when you get to your destination to pick up your object, lower it, strap it down, and you are good to go. Next I will show you how the hinge mechanism works. As you can see, we have a nice detail on the bottom side of the carrier. As you can see, it has all steel frame construction on the bottom, yet the polypropylene carrier itself makes it lightweight. And basically, there you have it for part number 7507, from Rola, the 22x56 inch folding polypropylene cargo carrier.
