My college has a small climbing wall in a gym. The athletic director has set it up with static 10mm ropes and claims, that because of insurance, all belayers must be clipped into a ground anchor. I think this sounds very dangerous, because there is nothing dynamic in the system. Even though it is only for top-roping, a small fall with slack in the system will result in a large force. I have never seen a commercial climbing gym require belayers to clip into the ground, nor have I seen static top ropes that often. Anyone else agree with me? Is this system safe?
