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]

Relationship to Captains of Crush

Left-Turn belongs to IronMind's CoC-compatible training range. Its distinguishing features are the reversed spring and black finish. See Captains of Crush for the standard range.[1]
