How it works

  1. Lock Your Hands In. Build Better Swing Mechanics.

    The strap keeps your hands working as one unit from load to finish. Every rep reinforces the correct bath path, so mechanics stay locked in every time. 

  2. Create Better Connection. Generate More Power.

    When your swing stays connected, you don't lose energy. The 9 STRAP immediately places your hands into the correct slot - leading to more consistent, hard contact.

  3. Stop Casting Your Hands. Drive Through the Ball.

    The strap gives instant feedback the moment your hands drift away from your body. By eliminating casting, you stay short and inside the baseball, creating ideal adjustability and consistency.

FASTER BAT SPEED

Hands cinched together lowers the moment of inertia. The barrel whips through the zone with more speed and higher exit velo.

ELIMINATES ROLLOVERS

Locks hands palm-up/palm-down, making it nearly impossible to roll over. More balls squared up, more barrels.

PREVENTS INJURY

Keeps both hands connected through the full swing, reducing strain on the shoulder, elbow, and wrist. Cuts bat-to-catcher distance by up to 30 inches.
