The 576780 is CERTI-CRIMP premium grade heavy head hand tools (HHHT) for crimping terminals and contacts on to large coaxial cable and heavy gauge wire. These CERTI-CRIMP premium grade hand crimp tools are designed to high specifications using high-quality materials to produce high-quality consistent terminations with optimal electrical and mechanical performance. Premium grade hand crimping tools require minimum operator skill to produce high quality crimps to specified parameters. Each hand crimp tool incorporates crimping dies, locating and straightening features that enable the terminals crimped by these tools to meet requirements of applicable TEC application (114-) specifications. The CERTI-CRIMP heavy head hand crimp tools for crimping AMPLI-BOND, PIDG and PLASTI-GRIP terminals feature insulation crimp height adjustment. Locators and wire stops are included on the tools where applicable. The whole design of the CERTI-CRIMP heavy head hand crimp tool ensures that the dies are bottomed independent of operator technique, fatigue or tool wear & tear. The crimp tool features a CERTI-CRIMP ratchet which is factory set to stay locked until the handles of the tool are fully closed and the dies are bottomed. This ratchet mechanism ensures that the tool only opens once a complete crimp cycle is achieved preventing partial crimps. The handles of the crimp tool are set to specific pressures to meet different crimp force requirements. To aid identification, colour coding or wire size information is displayed on the head or handles of the crimp tool.
