When you use Premium Strap Winder, you save yourself a lot of time and avoid a lot of unnecessary frustration. Our Premium Strap Winder is made of all steel construction with a zinc plated finish to give it that extra protection against corrosion. It can easily fit to the trailer side rail and can be wound in either direction. Simply clamp the Premium Strap Winder to the side rail of your trailer, feed the 2", 3", or 4" winch strap webbing through the slot on the winder and then start turning. The strap will quickly wrap around the Premium Strap Winder and roll up for easy storage.
