Cannon Sports heavy duty baseball/softball batting tee is built to take a beating. The batting T is height adjustable ranging from 21 inches to 39 inches. This is our best selling and most popular baseball T because it uses thick high grade black rubber and has a metal tube support, which is superior to the plastics used by the competition. The home plate base is heavy and durable to prevent the batting tee from tipping over due to batting swings under the ball. This batting tee is the sturdiest on the market.
