The 9 STRAP forces the hands to be cinched and locked together, thus reducing the moment of inertia, and therefore increasing bat speed and exit velocity.

With the hands locked together in a palm up/palm down position, the 9 STRAP makes it nearly impossible for hitters to roll over, ensuring more balls are squared up. 

The 9 STRAP ensures the bottom hand (the faster of the two) is pulling the upper hand through the zone, keeping the hands closer to the body and staying inside the ball. 

By maintaining a secure grip, and keeping both hands connected throughout the entire swing, the 9 STRAP gives the hitter more control, as though the bat is an extension of the arm.

9 STRAP technology prevents and corrects major swing flaws, such as: Casting, Leaking, Disconnecting, Rolling Over, Barrel Dumping, and more. The 9 STRAP promotes good balance and batting posture, optimizes bat path, generates more power, and increases overall swing efficiency.
