You won’t have to knock on wood that children will love the Free Play Treehouse Tube. Nature-inspired grain lines and plank like ends lend the entire piece of equipment a rustic feel. It looks like it could have been hewn out of a log and then had wooden planks placed around the entrance. Kids will feel like they’re crawling into a secret clubhouse. Both ends of the tube are secured in place with powder coat painted steel posts. Add a level of whimsy to your Free Play Treehouse Tube by selecting any combination of our rotationally molded plastic colors to pair with our steel posts. The Treehouse Tube looks like it came from an alien planet or out of a favorite childhood book. The Free Play Treehouse Tube can be incorporated easily into a new or existing playground with its small size.
