RECTANGULAR IN-GROUND TRAMPOLINE SYSTEM (14X10 FT)

The TDU retaining wall system was designed to be able to accommodate any ROUND trampoline Size. The standard kit is 33 interlocking panels, for a 14ft. Trampoline. The kit comes with self tapping screws to mount the kit to your trampoline.

If you have a smaller or larger round trampoline, please specify when ordering as we can send you fewer or additional panels depending on the size. ** Our 14' kit works perfect with the 14' round trampolines. Our 12' kit has 29 panels and 15' kit has 36 panels. The 12' and 15' systems may require that you overlap the final panel instead of interlocking the final panel...this is typically due to varying manufacturer sizes. The overlapped panel can be secured with the provided screws, and once backfilled will function properly, and will not be noticable. Due to the design of the interlocking system, it will not work for OCTAGON or RECTANGLE trampolines.

No it does not. However, we recommend a well built trampoline, and suggest that you stay clear of a cheaper light weight trampoline.

When putting a trampoline in the ground there is added stress on the frame, and therefore those with weaker frames tend to lose shape and have problems early on.

We Manufacture the Only IN-GROUND SpecificTrampoline in the Industry- we recommend you take a look at the VPS Trampoline by TDU Systems.

TDU will offer a compatable Safety Net Summer of 2017. Stay Tuned! ** Currently standard safety net enclosures do not work with our retaining wall system - unless you alter the product, to accomodate the installation.

Our Safety Net will be a BOLT ON SYSTEM- that can be installed after our Trampoline is already installed in the Ground! We are Super Excited for this one!

The TDU retaining wall system was engineered and designed for its specific purpose. If installed correctly the TDU system will outlast your trampoline. We will replace any damaged panels within the first 10 years at no cost if it can be determined that the system was properly installed. (excluding damage from severe acts of nature)

The TDU VPS GEN2 Trampoline comes with an INDUSTRY LEADING 5 Year warranty on the frame and springs, and a 2 year warranty on the Jumping Mat and Vented Safety Pad. **Keep in mind all Trampoline Manufacturers will void your warranty if you put their product at Ground level- this is quite simply because of the Increased wear and tear and Added Exposure to ground Moisture, sprinklers, lawn maintenance, and foot traffic on and off. The Warranty includes any Manufacturers Defects, and TDU will review each case and has the option to either repair or replace the product based on the defect.

One of the most common concerns of putting a trampoline in the ground is losing bounce quality. There are a few factors that play into this theory.. 1st the quality of the trampoline. A cheaper trampoline, with a poor quality jumping mat, and lower spring size/ count will not bounce as good as a better built trampoline, and will be even more noticeable when placed in the ground with air not being able to escape. The 2nd factor is the airflow restriction: An above ground trampoline has very limited airflow restriction as the jumper bounces- when you place the Trampoline in the Ground- and enclose it with a retaining wall system- the forced air of a bounce, trys to come back up through the jumping mat and springs- which is where our PATENTED Vented safety comes into play- Our Pad increases airflow, and allows for a much more similar feel to an above ground trampoline- than a trampoline without a vented pad does.

The TDU Retaining wall system needs to attach to the top ring of the trampoline for support, so you cannot install the trampoline above the kit for additional air flow. You can however leave the kit and trampoline above grade a few inches if you would prefer to have a better edging surface, so to not destroy your safety pad with your edger or mower. Trampolines Down Under recommends installing the Trampoline Flush at Ground level to help prevent injury.

Depending on your local soil conditions, it is usually recommended to use both dirt and gravel for your backfilling on the inside of the Trampoline Pit. Gravel will create a sump effect that will help prevent standing water.

Depending on local soil conditions, and the grade and location of the Trampoline Pit in your yard you may need to consider additional drainage solutions. In some cases we have suggested a French drain in the center of the pit, and in severe water circumstances an electric sump pump that could pump the water to the surface of the yard as needed.

Depending on soil conditions, and the climate you live in we recommend a few tips that can help. If you have a very soft clay based soil, we recommend using some block or compactable road base below each of the four legs on your trampoline- this will help prevent the legs from sinking into the ground.

When installing the trampoline into the ground, an easy way to ensure the trampoline is level (if you do not have a laser level) Is getting a 12ft 2x4 and setting it at an angle across the top bar at each leg angle. Then place a Level on the 2x4 and adjust accordingly. Do this at 4 different angles around the trampoline to ensure it is properly level PRIOR to backfilling the inside of the trampoline.

It can be done with one person, but at least two people are recommended. The instructions show to raise the system up to the trampoline top ring, but it is easier (if you only have 1 or two people) to set up the trampoline frame, then the kit around the trampoline, then rather than raising the kit to the ring, remove two legs and drop the Trampoline top ring down to the level of the kit. Place a few screws then take off the other two legs and drop the Trampoline frame on that side and place a few screws. Then put the legs back in and set the remainder of the screws one per panel.

A 14ft TDU Retaining wall system comes in 3 boxes (29x21x9") Each box weighs 50lbs. The kit costs $65.00-95 to ship, depending on location and can be picked up locally or at our dealers in the Trunk of most automobiles. If our Trampoline is ordered with the Retaining wall the Entire order will be shipped via LTL Freight on a pallet-

The TDU Retaining wall system is the ONLY patented Ground level trampoline system in the industry! There are other "methods" that can work but are more labor intensive, more expensive and they all have draw backs to using them.. here are a few of the attempted methods in the industry and why they are not as effective.
