The K Zone Strike Zone is perfect for both blitzball or wiffleball use! Strike Zone Target: 28 in x 27 in strike zone for backyard plastic baseball games such as Wiffleball and Blitzball. Includes multiple height options to fit any size blitz ball and wiffle ball user. Made with metal and durable vinyl that resists damage even after repeated strikes from blitz balls and wiffle balls. The K Zone Strike zone target is designed to last! Even better, the K Zone comes with easy assembly (no really, we promise). The 3 step assembly process is simple. Unwrap, attach the strike zone to the support legs, and insert the bolts to fasten. Faster than a fastball to install! The K Zone also comes with three separate height options to fit any size blitzball or wiffleball user. Strike zone is the perfect size and shape for your game! And while The K Zone is both wiffle ball and Blitzball compliant, the strike zone is not built to handle baseballs or softballs. Plastic use only. The Blitzball Strike Zone makes a distinct noise when contacted by the ball, allowing for a clear indication whether the pitch was a strike or not.
