Designed for medium to heavy oil.
The extended finger produces more rotation of the wrist during the release, generating increased length and backend hook angle by creating more side roll.
Straight wrist position with extended index finger support aids bowlers with inadequate side roll to create sustained hook and a greater angle of entry in the pins
Constructed of lightweight, duraluminum
Allows finger movement
Easy to remove between frames
Helps bowlers suffering from wrist pain maintain a consistent release
