Picking the right arborist ropes is crucial for a successful and safe tree-climbing experience. There are three main types of arborist ropes: climbing rope, rigging rope, and bull rope. Climbing rope is the most important type of rope, as it is the only type of rope that can be used to safely ascend and descend a tree. Rigging rope is used to secure climbing ropes and other equipment to the tree, and bull rope is used to lower branches and limbs.
