Innovative press-n-slide button allows you to adjust the jaw in a flash (up to twice as fast as traditional tongue-and-groove locks). Multi-groove ratcheting system enhances overall adjustability, enabling more precise fastener sizing. MIM (metal injection molded) precision parts ensure first-class jaw alignment and superior overall strength. Anti-pinch, non-slip ProTouch grips protect your fingers and maximize comfort while minimizing the potential for hand fatigue.
