Precision grip for handheld bow releases

Inconsistent thumb placement affects every shot. Even small changes in pressure can change your break and your impact. ThumbLock is a patent-pending sleeve that slides over your release’s thumb barrel to create a consistent, repeatable anchor— improving control, comfort, and confidence shot after shot.

Why It Works

Thumb placement directly influences trigger pressure and shot execution. ThumbLock’s ergonomic contour increases surface contact and guides your thumb into the same position every time—reducing torque, minimizing fatigue, and promoting cleaner breaks.
