King of the Swing Interchangeable Mounting Kit

This is an add on package! Your Ground Force Trainer will come with the pitching rubber or hitting pad kit depending on the model you order. This option will allow you to transform your King of the Hill or Queen of the Hill model into a King of the Swing model. 

The Ground Force Trainer is a great device for pitching, hitting, and fast pitch softball pitching! The Ground Force Trainer can be used for one use, or multiple, and altered easily with the purchase of an additional kit. You will receive the hitting force pad, and a wrench to change out the kit whenever you’d like, without having to purchase another unit!
