The Franklin Sports rubber tetherball is designed for serious swinging action. Constructed with a tacky rubber cover in official 8.5 inch size, the butyl bladder and extra winding ensure the ball will retain its shape for long lasting competition in the school yard, at camp your own backyard or on the playground. The recessed metal post ensures a simple set up for the 9' cord that is included. Thanks to the vibrant yellow color, athletes of all ages serve, strike, block and track the ball as it swings around the pole to win.
