These Grade A manila climbing ropes are individually handcrafted with a technique known as splicing, the attachment end is braided back into itself to form a 6" loop. The spliced loop of these climbing rope forms a superior method for attaching the rope with a safe weight load limit of over 5,000 pounds, in short, it'll hold up under the toughest conditions.The loop end is covered with a heavy duty nylon fabric to protect the loop from fraying. The opposite end of our climbing rope is finished off with a heavy duty vinyl handle to also protect the rope from fray. These manila climbing ropes can be used either in-door or out-doors; the manila fibers make for an easier climb up the rope but are tougher on your hands. We've also found that over time and with use, the rope will soften up and will not shed as many fibers.
