Toproller- Open Style

The Toproller – Open Style is a purpose-built grip attachment designed to develop crushing hand strength, finger control, and dominant top-roll mechanics. Its open design allows for a more natural hand position while emphasizing finger engagement and pronation, making it ideal for armwrestling training and advanced grip work. Built for durability and smooth rotation, it connects easily to cables or loading pins, giving athletes a versatile tool to target back pressure, wrist control, and overall pulling power.
