These System Half balls are 140 mm in diameter and are actually a little over half at 80 mm in depth.
System Half Balls are manufactured with precision and care for a tough but rewarding training experience in open hand pinch training.
Setup on a campus board is where they are most effective. In conjunction with Awesome Woodys Sloper rails and campus rails they create the epic training
They can also be used as a stand alone set or also as regular holds on your bouldering wall.
