The Ivanko Super Gripper

I have noticed in a workout log that someone is using this device with springs in the 11 and 12 postions. I have two of these units, and have tried to get the springs in this position, and find it IMPOSSIBLE. There is just no room. I recall this being brought up before by someone, then we were back to seeing the springs at 10 and 12 for a time, now it's back to 11,12.

I tried a wall model at the local fitness retailer over the weekend and was met with the same insurmountable situation.

I am curious to know if some of these units did indeed have narrower springs at one time. Is this an example of Super Grippers varying? or bat-guano? ;)
