A Bungee pit is a polypropylene trampoline bed that is suspended about three feet above the bottom of a six-foot deep pit using bungee cord. Three feet of pit foam is then placed on top of the ploy' bed in order to provide a safe, cost effective alternative to conventional foam pits (see diagram and picture below). Consider the following features and benefits of a bungee pit: SAFETY: The bungee bed is suspended three feet above the bottom of the pit. Thus, there is no way to hit the bottom of the pit! COST: You will use about 40 percent less foam in your pit! The cost of the trampoline bed and bungee cord is far less expensive than filling the entire pit with foam. You can save thousands of dollars on a typical size pit! PRACTICALITY: The trampoline and bungee cord will automatically "fluff" the foam in your pit. You spend less time taking the foam in and out of your pit. CLEANLINESS: The residue of foam will tend to settle under the trampoline bed. You will have less dust coming out of your pit and have a cleaner gym. PRICE: The price for a bungee pit system will depend on the size and shape of your pit. Please call, write, e-mail or fax the specs of your pit and we will gladly provide you with a no obligation price quote. Hope to hear from you soon.

Parts List & Installation Instructions for the L-Shape Bungee Pit

YOUR BUNGEE PIT WILL INCLUDE THE FOLLOWING ITEMS (8’ by 30’ L pit):

1. A polypropylene bed with 1” loops sewn every 5” around the perimeter and 10” flaps that extend beyond the 1” loops. The bed will be about 12” smaller on both sides and both ends than your pit. In the following notes P=perimeter in feet=84; A=area in ft²=272.

2. 3.50*P feet of 0.5” bungee cord and one bag of hog rings. Thread the bungee cord through the 1” loops and secure the two ends with the hog rings. Put an S-hook on each end of the cord just up stream of the hog rings. Leave a 6” loop of B-cord between each 1” loop. Notes: you will need to adjust the length of the bungee cord in order to get the proper tension in the poly’ bed; it is best to cut the bungee cord into lengths of about 25 feet and work on opposite sides of the pit (versus threading one long piece of bungee cord!). For this example use 300’ of bungee cord and 25 hog rings.

3. 2.67*P “S”-hooks to stretch the bungee cord from the poly’ bed to the angle iron bolted to the wall of your pit. 250 S-hooks.

4. P feet of 2” by 2” angle iron[1]. One leg of the angle iron will have “monkey wire” with loops every 2.5 inches. The other leg of the angle iron will have 7/16” holes every 18” (3 holes per 4 feet). For this example you will need 21 sections of the 4’ angle iron.

5. P feet of 1/8” bungee cord. 100’.

6. Concrete wedge anchors, 3/8" by 3.75". 3 anchors per 4' section of angle iron. You will also need a hammer drill (rent one, if possible).

TO INSTALL YOUR BUNGEE PIT:

1. The angle iron should be bolted to the walls of your pit three (3) feet below the floor (if your pit is less than 6’ deep than put the angle iron half way between the top and bottom of your pit). Rent a hammer drill; note that the angle iron has three 7/16” holes per four-foot section; use these holes to mark the walls. TEST ALL BOLTS BEFORE PROCEEDING TO STEP 2.

2. Lay the bed in the bottom of the pit.

3. Use the S-hooks to stretch the bungee cord to the monkey wire welded to the top of the angle iron. Adjust the tension such that you can jump in the middle of the bed without touching the floor of the pit. Also check the integrity of all the mollies.

4. Lay the 10” flaps over the bungee cord. This will prevent the foam blocks (or little munchkins) from squeezing in between the bungee cord. Use the 1/8” bungee cord to loosely tie the flaps to the monkey wire.

5. Fill the pit with your foam blocks and have fun!

2” by 2” Angle iron with 7/16” holes & monkey wire:

As an alternate to using the hog rings to secure the ends of the bungee cord, you can simply tie a knot in the end of the 0.5” bungee cord:

Lace the bungee cord through the loops on the poly’ bed and secure to the monkey wire using the S-hooks:
