The high-performance RockSolid anchor features an innovative bronze wedge assembly that expands and exerts continuous, even pressure on the platform post - eliminating "wobble"! You can easily tighten the anchor prior to a race to prevent the platform from rocking, or loosen the anchor to remove the platform for storage. Use the included anchor cap to give the deck a flushed look when the starting platform is removed. The RockSolid anchor is available in a 6" single post design or an 8" single post designed to be used on pool decks with pavers.
