AAI is now recommending the use of AAI vault boards with fewer springs for Level 4 gymnasts that weigh less than 80 lbs. As few as 3 springs on either the Stratum Vault Board or the TAC/10 LZT Vault Board are now acceptable. However, ensure that the two front corner springs (high side), as well as the center spring in the middle row, stay in their original position as you can see in the following diagram.
There are eight spring positions available on the board. Each board ships with 6 large springs and 2 small springs (8 springs total). The number of springs and their positions can be adjusted to meet the needs of the gymnast’s weight and ability.
For approved FIG spring configurations, please refer to the following 8-coil, 6-coil and 5-coil spring configuration diagrams:
To remove a spring, stand the board on end with the legs facing you. Place your thumbs on the leg for leverage and pull the top coils of the spring away from the rubber bumper. To insert the spring, place the spring in the board pushing down on the top coils until it pops over the rubber bumper.
Inspect the springboards periodically for loose fasteners or other damage. Do not used damaged equipment. Contact American Gymnast at 1-877-789-2267 for repair or replacement.
