The Cargo Rack comes with Hornet Twist Lock anchors (2). The anchors insert in to the bed holes on your Ranger. When you tighten them the anchor expands in the hole and it's tight! The rack won't bounce out. The rack comes with 2 anchors but the base is drilled with 2 more holes so, if you want to add 2 more anchors you can certainly do that. On my Ranger I use the two anchors that came with it and it's solid.
