The GFX-2311 is a classic, professional-grade torsion spring gripper built for athletes who demand maximum durability and an unyielding grip. Moving away from plastic-handled expanders, this model features solid aluminum handles enhanced with a precision machine-cut diamond knurling pattern. This texture bites lightly into the palm, ensuring an entirely slip-free hold even during intense, sweaty workouts.

At its core is a high-tensile, black-coated steel torsion spring calibrated to a fixed 100 lbs of resistance. This makes it perfect for intermediate strength training, martial arts conditioning, climbing prep, and deep forearm hypertrophy. Combining a sleek, professional aesthetic with rugged materials, it is built to survive a lifetime of heavy use without losing its tension.
