The Wing Clip II is a swing training tool created to curb the tendency of bending the lead arm. Designed for smaller arms, The Wing Clip II is perfect for women and youth sizes. The Wing Clip II attaches to the lead arm with 3 Velcro straps. The device fits on the inside of the arm and locks the elbow down with a 1-inch middle strap. The middle strap is secured, while the arm is straightened, covering the knuckle of the elbow. You will notice a slight dip in the contour of the middle of The Wing Clip II. This indenture fits comfortably in the underside of the arm.
