When your youngsters have mastered your vertical wall and are looking to give them a new challenge, the Hula Hoop Holder does the trick. By installing this product so that the channel is vertically oriented, a hula hoop will snap-in. As the climber passes through the hoop, if they fall, the hoop will release. A hula hoop is not included, and we recommend you take this product with you when shopping for one. We've found that some of the Walmart products will fit.
