Speedball's plastic Bats have a smooth edge that makes it easy to lift away from the wheel to transport the thrown items safely to the drying rack. Speedball's Bats fit all wheels that have holes. Screws are needed to attach them to the turntable. 

The bats are available in three sizes: 

SP75 is square and 19 x 19 cm. 

SP12 is 30.5 cm in diameter. 

SP14 is 35.5 cm in diameter. 

They fit wheeels with distance between holes of cc 22.5 cm and cc 25.5 cm as they have two different attachments for screws with two different dimensions on the underside of the kit.

It is recommended to store the kits on a flat surface and cleaned on each other to prevent them from bending during longer storage.
