Finger Grip Strengthener Ball

99 LB Eagle Claw Hand Trainer

This finger grip strengthener features an eagle claw design with five individual spring-loaded buttons that target each finger independently. Built with a carbon steel spring mechanism rated at 99 LB (45 kg) resistance, it delivers consistent tension for hand strength training, injury recovery, and finger rehabilitation.

Eagle Claw Grip Trainer for All Five Fingers

Each button operates on its own carbon steel spring, allowing targeted finger exercises that build grip strength, forearm endurance, and hand dexterity. The ergonomic button spacing fits natural hand positioning for rock climbers, guitarists, baseball players, and martial artists.

TPE + ABS Construction with Carbon Steel Springs

Soft TPE rubber finger buttons provide comfortable grip during extended training sessions. The ABS outer shell with soft paint finish resists wear and maintains a non-slip surface. Internal carbon steel springs press smoothly and rebound automatically without jamming.

Hand Exerciser for Rehabilitation and Strength

Designed for injury recovery, stress relief, and progressive finger training. The compact spherical shape fits in one hand and travels easily to the gym, office, or physical therapy sessions.
