Captains of Crush Left-Turn
Left-Turn is IronMind's reverse-wound gripper line. It uses black anodized aluminum handles and GR8-L springs, with IronMind markings in the central handle band and the model on the handle end. The grippers are made in the USA.[1]
What “Left-Turn” means
IronMind describes ordinary Captains of Crush springs as left-hand wound and Left-Turn springs as right-hand wound. The product name refers to the intended left-hand feel, not the engineering name of the spring winding. Either type can be used in either hand.[1]
Models
| Model | IronMind's approximate advertised resistance |
|---|---|
| Trainer | 100 lb |
| No. 1 | 140 lb |
| No. 2 | 195 lb |
| No. 3 | 280 lb |
These are manufacturer figures, not individual RGC ratings. For example, Cannon PowerWorks lists a 150 lb average measured rating for the Left-Turn No. 3 while explicitly distinguishing its 280 lb manufacturer label.[1][2]
