Ivanko Super Gripper
Out of the box, the Ivanko Super Gripper has forty increments of adjustable resistance using two beefy coil springs. The Super Gripper solves the problem created by the big jumps of the non-adjustable grippers. Add some variation by using it in the 'conventional' or 'original' holds. You can adjust the load over a wide range quicker then you can add a pair of plates to a bar. The Ivanko Super Gripper is a compact, affordable, versatile, portable all around grip tool.
