Ratchet strap winders use a simple mechanism that can wind a strap for storage without mess or knots. Simply insert the end of the ratchet strap into the holding device and make sure it is held securely. Then, turn the handle, and the strap will start to wind around the core of the ratchet strap winder. Once it is fully wound, you should be able to remove the strap from the winder without issue.
