A ratchet crimp tool or ratchet crimper is used for crimping connectors onto the ends of wires or cables. Ratchet crimp tools have a ratcheting mechanism which allows consistent and controlled pressure to be applied during the crimping process ensuring that a secure connection is made. The handles of a ratchet crimp tool will not release until a full crimp cycle is completed preventing faulty and weak connections that can be caused by incomplete crimps. Ratchet crimp tools are used in a wide range of industries where large volumes of reliable crimps need to be made including electronics, automotive and telecommunications industries.
