Kids love tubes and tunnels. They create a unique play and exploration element to any playground. Our KidNetix Net Tube takes the play value of a regular crawl tube to a new level! The 41” diameter end rings are constructed of 2” diameter aluminum tubes that help keep the structure taut and provide a stable point of entry and exit. The tunnel is constructed from 12 horizontal rope strands and 10 rope hoops. The tunnel is suspended from the uprights with four ropes that allow the net to move and sway as children climb through the tunnel or along the exterior of the tube.
