Climbing ropes have been used for training and exercise for hundreds of years. They are still used by virtually all branches of the military, police and fire academies and in schools for physical education (PE), as well as physical conditioning for all sports programs. Climbing ropes give you great endurance, upper body strength and incredible grip strength. Ropefit's climbing ropes are made with high quality poly dacron rope, that can be used for indoor and outdoor climbing. Manila rope, which is used by the majority of companies, will rot over time if used outside. Also if used indoor or outdoor, manila will develop 'rope splinters', which can end up in the hands and eyes of it's users. Rope Fit only uses high quality poly dacron rope, which will not develop 'rope splinters', nor will it rot when utilized outdoors. Rope Fit offers a large variety of pre cut rope lengths, however, we offer custom sizes at affordable prices. E mail or call for custom sizes. The length of the rope is from the top of the splice to the end tip. Warning! Rope climbing is inherently dangerous. Rope Fit LLC does not recommend climbing ropes without using several landing pads at the base of all climbing ropes. By purchasing this product with this warning being posted Rope Fit LLC absolves itself from any claims made while using Rope Fit LLC ropes.
