Ratchet cargo straps can tie down a load by securing it to the floor of a flatbed truck. They can also be used to tie down and secure a piece of cargo to the sides of the interior of an enclosed trailer. It can connect to anchor points in the side of a flatbed truck, like D-rings, and can also latch onto anchor points on the floor of the truck bed for easy tightening!http://www.herunsling.com/cargo-straps/
