Gibson's Mile High Spring Board provides an extra punch from its long-lasting, heavy duty 1/4" chromium-plated music wire springs. The thinner 1/2" maple top allows more flex, thus more spring. Top surface is padded with 3/8" closed cell cross-linked foam and covered with high quality carpeting. Webbing system adds greater lateral stability. Includes rubber pads. Meets all FIG, USAG, NCAA & high school specifications. Made in the USA.
