IVANKO Super Hand Grip Gripper Strength

Made of die cast metal and heavy duty coil springs, it’s nearly indestructible and very few parts means less to break. The thin design makes it easy to grip and won’t cut into your palm as you squeeze. It’s pretty big too and with the trigger style gripper, there’s plenty of room for your fingers no matter the size of your hand. The Ivanko gripper comes with two springs for beginner resistance but additional stronger springs can be added to give this device up to 40 different levels of resistance.
