The 59250 is a T-Head Hand Crimp Tool for AMP PIDG/STRATO-THERM/PLASTI 26-14AWG terminals and splices. The handle of the crimp tool is color-coded to match the color coding of the product to be applied. The insulation adjustment indicator is used to control crimp height of the insulation barrel. It can be set at any of four positions corresponding to insulation diameter. The CERTI-CRIMP hand crimping tool ratchet control ensures full crimping of the product. Once engaged, the ratchet will not release until the handles have been fully closed.
