The Polaris® Rear Rack Extender serves as a perimeter around the rear cargo rack of a Polaris® Sportsman® 570 and 450 ATV, keeping cargo from sliding off the rear platform. It mounts solidly to the rear cargo platform and integrates seamlessly with your ATV. Constructed from durable steel tubing, it also works as an anchor to tie down gear using straps or bungee cords.
