Ideal Ratchet Telemaster Modular Plug Crimp Tool is a professional grade tool designed for high everyday usage in the data and telecommunications fields by industry professionals. It has been an industry leading tool for crimping Cat5e and Cat 6 modular plugs for over 15 years. The precision ground crimp teeth and a multi-plated steel-walled body keep the connector stable and all the moving parts aligned throughout the crimp process for a perfect crimp every time. Many general purpose tools inconsistently crimp each of the eight contacts of a modular plug and the tool cavity can bend under crimping stresses. This results in weak conductor to pin contact points from contacts that were not fully seated. Uneven/unseated contacts can also cause damage to the mating connector port. The ratchet mechanism only releases when a full cycle crimp has been completed. It prevents under-crimping of the connectors and eliminates excess squeezing of the handles as seen in non-ratchet tools when the crimp has already been completed.
