The Frictitious Pulley System makes pulley-assisted training accessible to all climbers, offering a simple way to make incremental adjustments to your training. By attaching one end to your harness and the other to a weight, you can reduce body weight to assist and progress your weakest two-hand grips. For more advanced training, use your free hand with a weight for assisted one-arm edge training. This pulley features actual bearings inside, ensuring precise, consistent assistance—unlike cheaper pulleys that may lose accuracy. Perfect for building finger strength, this system provides accurate, incremental training to help you progress efficiently. The kit includes a high-quality pulley, cord, clevis pin for mounting, and a small cord loop for versatile hanging.
