The Tanner Heavy is a pro-level batting tee built to handle the demands of serious hitters. Its 10 lb. weighted “claw” base provides rock-solid stability on any surface—homeplate, turf, grass, or concrete—and stays upright and in place through mis-hits and aggressive training sessions. At the core is a reinforced steel stem engineered for long-term durability, season after season. Up top, our famous hand-rolled flexible ball rest delivers a clean, consistent feel at contact, so hitters can focus on mechanics without interference. Trusted by professional athletes and coaches, the Tanner Heavy is the ultimate tee for building swing after swing of solid contact.
