The550CordShop White PolyDac Climbing Rope Our poly-dac ropes are individually handcrafted with a technique known as splicing, the attachment end is braided back into itself to form a 6" loop Spicing is a superior method for attaching the rope with a safe weight load limit of over 5,000 pounds The loop ends of our climbing ropes are covered with a heavy duty nylon fabric to protect the loop from fraying The end of your climbing rope is finished off with a heavy duty vinyl handle to also protect the rope from fray Poly-dac ropes are great for both indoor and outdoor use, the softer rope makes for a more challenging workout as it's more difficult to hold on to
