16′ TDU Retaining Wall System



Our Retaining wall system was designed specifically for our Trampolines- HOWEVER the system will also attach to your existing round trampoline-  Please note not all Trampolines are created equal- Some less expensive trampolines with thin walled frames don’t have the strength to support the pressure from placing your trampoline in the ground. Please don’t hesitate to reach out to us with your brand model so we can help ensure our product will work well with your trampoline 

* Comes with hardware to attach to any round Trampoline and instructions on how to install the system.
