Original pro model Tanner Tee is comprised of two parts, an adjustable stem and a 9" weather resistant polymer base. The hand rolled rubber FlexTop sets Tanner Tees apart from any other training tool. Its flexible rubber allows the bat to pass through the contact point with the least interference, and provides instant feedback with every hit. It breaks down in seconds to fit into any travel bag and is sold with a 9 x 9" standard base with rounded edges for safety. Adjustable 26"-43" recommended for adult and youth ages 9 and above.
