The Wavy Straight Rung Overhead Climber is manufactured in the United States out of durable steel that is galvanized and powder-coat painted in a color of your choice. Overhead events are important to offer on public playgrounds, as children require a high level of physical fitness. The playground is at times the only way some kids get physical activity. The wavy design of the Straight Rung Overhead Climber provides added challenge from the standard unit. The bar slopes up and down slightly at angles for an increased challenge. The Sii Wavy Straight Rung Overhead Climber offers children the opportunity to perform climbing activities easily, joyfully, and most importantly safely.
