The ACUrope from TenPoint is an easy-to-use, fully retractable rope cocking mechanism that sets the rope of your crossbow faster than ever. Once the bow is cocked, the ACUrope's draw cord completely retracts inside one of the two grips. As soon as you're finished, simply fold the ACUrope into a compact dovetail shape for easy storage that is small enough to slip inside a holster. Removes tangles, knots, and other drawbacks found on traditional rope securers. The draw cords are made of heat and abrasion resistant SPECTRA 1000 fiber. Havey-duty springs are packed neatly inside the grips for immense power and control, mounted on a durable steel axle and frame. The ACUrope is composed of DuPont Zytel Super Tough Nylon. Black finish.
