A ratchet tie down that takes about 1/3 of the normal time to use! No feeding in; no tying off ends; no webbing removal from the ratchet. The strap is permanently affixed and self contained. The built in power spring automatically retracts the webbing for easy storage. Just press the retract button and the webbing winds in (just like a tape measure). It has a safe working load of 500lbs (breaking load of 1500lbs).
