Instructions for 12' IGT system
Step 1: IGT Site Preparation
Site Location
Several factors must be considered when choosing the site for your new In-Ground Trampoline (IGT) system.
Since local soil and weather conditions vary greatly from region to region, it is recommended that a local
landscape expert be consulted for placement of the system.
A minimum of 12 feet of overhead clearance and 5 feet of clearance from the trampoline to other objects on the
ground is recommended for the jumpers protection.
Using impact-absorbing ground cover such as grass, sand or bark chips is recommended for 4-6 feet around the
trampoline.
Drainage
Drainage is not a problem with our In-Ground Trampoline system.
It is recommended to leave 2-4 inches of the trampoline above the final grade and gradually berming the soil up to
the edge of the trampoline. This will keep water from flowing into the pit in the event of heavy rain. Depending on
local soil conditions you may consider adding 4 to 6 inches of rock into the bottom of the pit, creating a sump effect
to prevent standing water. You will need to excavate the center of the pit deeper at the same depth as the rock you
intend to add. Extreme conditions may require additional drainage methods or the use of a sump pump. It is always
a good idea to consult a local landscaper regarding local soil conditions and drainage for your area.
The Pit
The IGT system is designed to be installed partially or completely recessed in the ground.
Either way, the pit will need to be excavated to a diameter of at least13 feet. If the IGT system must be assembled in
the pit due to size constraints of the yard, a 14 foot pit is recommended for easier access to assembly hardware.
For a completely recessed system we recommend the excavation of the pit depth be 29-31 inches deep. See below
for Pit Dimensions. The system is a total of 33 inches tall so this allows for the trampoline to remain at least 2-4
inches above the grade as recommended in the Drainage section.
For a partially recessed system, the dirt excavated from the pit can be used to build up the area around the
installation. Excavating the pit to a depth of 18 inches leaves 15 inches of the system exposed. This method
eliminates the need for removing excavated soil from the property.

  • Page 2 Very Important Instruction Tips For Proper Installation -The IGT system must be set above the grade of the yard to prevent water from collecting in the trampoline pit. -The IGT frame must be completely level and round before and during the backfilling process.

  • Page 5: Step 3: Frame Assembly

    Lay Out Parts for Easy Installation Lay out parts as shown to simplify assembly of the frame. Use one of the shipping boxes to separate all the hardware. Step 3: Frame Assembly Tips Use the assembled lower frame ring as a template to help locate and mark for pit excavation.
  • Page 6 Step A: Assemble lower frame ring section. Assemble lower ring (frame tubes without spring holes) using the 12 lower frame tube segments. Step B: Join 3 wall panels with one top frame segment. Lay 3 wall panels on the ground overlapping each other so the holes are aligned. Attach the top holes of the panel (holes closest to the edge with the protector strip) to the upper frame tube segment using a bolt and washer on the panel side and a nut and washer on the frame side as shown in the photo below right.
  • Page 7 Step C: Join the 3 wall panels and upper segment to the lower frame ring. To make assembly easier, use the shipping boxes to support the lower frame ring about 6 inches off the ground while attaching the wall panels. Attach the assembly from step 2 to any place on the lower frame ring using a bolt and washer on the panel side and a nut and washer on the frame side.
  • Page 8 Step E: Complete the frame assembly. The final wall panel and upper segment installation may require lifting and/or shifting the frame. This is why the bolts should be left loose until the frame is completed. Be sure all edge protectors are properly seated prior to tightening the hardware.
  • Page 9 Step 4: Position Frame Assembly into Pit Install The frame can now be placed into the excavated hole. The completed frame weighs 235 lbs. (12’) and will require 3 to 4 adults to position the frame into the pit. Do not force the frame into a pit that is not excavated to spec.
  • Page 10 Backfill Backfill the frame assembly using the excavated soil. Try to use loose dirt free of large clumps. It is critical to back fill evenly. For best results add 8-10 inches of dirt all the way around the frame and compact. Check for roundness during the backfill process to make sure the frame stays good and true.
  • Page 11 Step 5: Install Jumping Surface Attach Every 4 Spring Using the provided spring tool, start at any point attaching every 4 spring from the frame to the rings on the jump mat, skipping 3 holes on the frame and 3 rings on the mat. The spring has a tight hook and an open hook. (See photo) Make sure the tight hook is attached to the jump mat first and then using the spring tool, pull the open hook and attached to the frame.
  • Page 12 Attach middle springs Attach the springs in the middle of the first round of springs Attach all remaining springs Make sure the springs already attached are correct. There will be a frame hole and mat ring for each spring. After the pattern is confirmed correct, attach the rest of the springs to the frame and mat.
  • Page 13 Step 7: Attach pad Edge protector Before installing pads, make sure the Edge Protector is properly in place Install pad Lay the pad out on the perimeter of the trampoline. Attach the Velcro ends together. At this point you must lie down on top of trampoline jump surface and lift up the edge of the pad to gain access to the Velcro straps located on the bottom side of the pad.
  • Page 15 You are now finished with the IGT installation!   Let them Fly, Keep them Safe!  • Falling off a trampoline is the number one cause of injury on trampolines. Instead of falling 3 to 4 feet off of your  trampoline, with our patent pending in‐ground trampoline you literally step off on to your grass or other impact  absorbing surface.     • We recommend a grass or soft wood chipped surface around the trampoline. Any impact absorbing surface will help  to keep you safe in the event that you fall off of the trampoline.       • We also recommend that only one person be allowed to jump on the trampoline at a time. When two people are on the  trampoline at once they can catapult each other or bump into each other. With two people on the trampoline the users  cannot bounce in the middle of the trampoline where the safety margin is maximized.              •       The area around the trampoline should be clear of all objects. Trampolines should not be placed near fences, trees etc.     ...
