The CHAMPRO 3-Spike Pitcher’s Rubber is a quick and easy way to get the mound set up for games and practices. Comes with three nickel-plated steel spikes that secure the rubber to the ground, keeping it in place. Reinforced, threaded steel spike fixtures hold the spikes in place without damaging the rubber. The 1cm thick, UV-resistant rubber construction endures the elements and spiked shoes for seasons. Available in Official (6"x24") and Youth (4"x18") sizes to suit every age and level of play.
