Spiral tube slides are favored equipment for older children, and at 8 feet tall this slide is built for fun. This playground event features an easy access stairway and giant tube slide with multiple support arms. The 3.5-inch steel posts and tube come in a variety of colors. Built to meet all commercial standards for playgrounds. A 5-inch post is available. The difference in post size does not add to the stability of the structure, only to added aesthetics of the playground, overall appearing much larger.
