This slide is available for use with play areas with 15-foot deck heights. This slide is designed for custom commercial installations, so no installation directions or diagrams are included to ensure installation is completed by a professional contractor. The slide is 30 inches in diameter, and can include up to five twists or spirals depending on the overall design options chosen. You will need to include whether you require a counter clockwise or clockwise rotation when ordering. The slide is made of durable rotational molded polyethylene for a durable matte surface that resists fading and damage. Slide is available in numerous color options to assist with custom designing. In addition, the galvanized steel supports are available in a wide range of colors to facilitate complete customization of colors to match nearly any color scheme. All orders include only the slide and galvanized steel supports.
