Winches, also known as Truck Winches, Webbing Winches or Trailer Winches, are used to secure and tie-down your cargo load on your truck and trailer. They have different styles with the most standard being weld-on, sliding, and bolt-on.
Winches have a slot for the webbing to go through so it is secured to the winch. And each winch has a round hole where the winch bar can be inserted to tighten the strap or load down.
These two product come hand in hand, and are the most common cargo tie down systems for flat bed trailers.
