The Walter Klassen Crossover Block connects a carbon arm to your Walter Klassen harness. It is available in both left and right orientations with an optimized 7 degree angle. Crossover Blocks can be configured to be swappable, allowing different operators to share a harness and Carbon Arm.
Specify a left or right Crossover Block based on the which side of your body the carbon arm is positioned. Having one of each Crossover Block is recommended if you frequently switch sides.
Each Crossover Block order includes a spare push nut.
