The Air Door is a part of our NEW Air Obstacle line for G2N! The products in this line make for unique additions to your ninja rig that will put your ninja's abilities to the test. Jump from the Air Hanging Door to the next by using the foot ledge at the bottom and grabbing the handles on the sides. The large circle cut out in the middle provides another way for you to grip on without falling. This obstacle is a tricky one but one you must have to grow your ninja skills!
