ONE GRIP STRENGTHENER TO RULE THEM ALL Introducing the most versatile, durable and effective grip and hand strengthener ever created. SILENT - Our solid steel compression spring is designed to be completely silent when compressed. You'll never have to worry about the squeaky sound that plagues other grippers. You could train with your GD Iron Grip next to a sleeping baby, and they would never even know you were there. VERSATILE - With a resistance range of 55-198 lbs (25-90 kg), the GD Iron Grip gripper can offer a level of resistance that can challenge both beginners and veterans alike. Regardless of your current grip strength, you will find levels of resistance that will allow you to see dramatic improvement while challenging you every step of the way. QUALITY - Crafted 100% from stainless Steel and Aluminum, you can feel the quality the instant you pick up the GD Iron Grip grip strengthener. There is no squeaky spring, no side to side wobble and the resistance only adjusts when you want it to. SAFE - By using a compression spring design, we've eliminated the danger posed by adjustable grippers that create resistance by stretching a metal spring. Stretching a spring places a tremendous amount of tension on the spring and the anchors holding it in place. When that much force & potential energy is placed on weak metal & plastic components, they will eventually fail, sending dangerous debris flying through the air. This single gripper provides resistance from beginning to professional levels.
