VERY POPULAR CLIMBING ROPE AND SWINGING BASE COMBO: The sturdy base helps children climb up the rope more easily, as do the climbing holds on the rope. The base can also be used as a swing seat around which the children can place their legs and swing back and forth. The 3 climbing holds make the rope a great and challenging obstacle. Can be easily attached to a ninja or swing set ratchet strap, playground equipment, or even tree branches.
