This 17 "x17" baseball training home plate size (17 inches front edge x 17 inches side edge x 12 inches back width) features a precise pentagonal cutting design, providing players and coaches with a realistic game scene training experience. Made of crack resistant rubber material, it has excellent weather resistance. The innovative red, yellow, and green mixed surface forms a visual training system: the 8-inch red core area focuses on precise pitching training, the yellow transition area cultivates the ability to judge the ball band, and the green edge area strengthens the recognition skills of out of bounds balls. The plain weave anti slip base design ensures stable grip on artificial turf, concrete, or indoor flooring without damaging the surface. The whole board weighs only 0.6 pounds (70% lighter than traditional 5-8 pound home plates), and comes with an Oxford cloth storage bag with waterproof function, making it particularly suitable for daily training, sports courses, and home training. The 1.2-inch tapered edge eliminates the risk of tripping and can perfectly cope with harsh environments such as daily training, rainy season training, or coastal leagues that can easily cause deformation and cracking of ordinary home plates. Whether for bullseye pitching training, standardized hitting posture correction, or as a multifunctional marker board for softball/soccer, this all-weather training board can provide professional level training effects, making it an ideal choice for parents and players to cope with training plans and adverse weather conditions
