About Our System

Our product is a light weight, durable plastic molding, with a patented self locking buckle system. These features allow the user to snap the system together in MINUTES!  The TDU System is the ONLY patented in-ground retaining wall system on the market today!

Installation of our kit allows the user to install their trampoline at ground level while retaining the surface from collapsing under the trampoline. This surface retention system also allows a flush transition from the trampoline ring to the ground, making edging, and yard maintenance a breeze!

Safety

Our ground level system dramatically reduces the injuries associated with trampolines, by eliminating falls to the ground, reducing the height above the ground while jumping, and eliminating injuries to children walking under the trampoline while others are jumping.

Our product offers a rounded surface that fits snug against the ring of the trampoline, eliminating the razor sharp edges that are exposed when using metal retaining wall system.

Trampolines that are above ground, especially those with safety nets are an easy target for severe damage during a wind storm. Our kit will virtually eliminate the possibility of having the wind carry away your trampoline.

Installation Instructions

Step 1

Prepare a hole 1 ft. larger in circumference than the trampoline, and 3 ft. deep.

Step 2

Secure inter-locking panels to the top ring of the trampoline using the self tapping screws provided in the kit (as shown in the diagram to the right).

Step 3

After the panels have been secured around the trampoline frame, it is now ready to be placed in the pre-dug hole.

Step 4

Once the trampoline frame is level and flush with the surrounding grade, backfill the inside perimeter first (A) with dirt or gravel to the mid-point of the panel then backfill the outside (B).

Step 5

Install the trampoline mat and safety pad then enjoy your new in-ground trampoline!
