Forged for Maximum Strength
Each electric locker is equipped with precision-engineered forged gears, crafted from high-grade alloy steel. The forging process refines the metal’s grain structure, greatly increasing impact resistance and fatigue life. This ensures unmatched durability under extreme torque loads, delivering instant, reliable locking performance wherever the trail takes you.
