The Stratum® Vault Board, 8-Spring Hard Version is designed to deliver a firmer, more powerful rebound for gymnasts who require increased energy return during vault training and competition. As one of AAI’s most popular vault boards, the Stratum® line is known for its predictable response, durability, and competition-ready performance.
This model features a non-removable 8-spring configuration that provides a stiffer feel compared to softer boards, making it well-suited for stronger or heavier athletes. Black oxide springs deliver consistent rebound, while the robust fiberglass base and padded carpet surface ensure long-term durability.
This vault board meets FIG specifications and is approved for use by USAG, NCAA, NFHS, and AAU, making it suitable for all levels and both training and competition environments.
