The Top Hopper Extension Plate ensures you can measure every athlete's vertical jump height regardless of how high they can jump. By simply attaching the Extension Plate to one of the three mounts and then attaching the Top Hopper Measuring Device to the Extension Plate, this will raise the TH1000 measuring device 24 inches higher. Once completely assembled, measuring the athlete's vertical jump is accurate, repeatable, reproducible and most importantly safe. The Top Hopper Extension Plate is powder coated to help protect the steel from the environment and looks great.
