The Telemaster™ has been a best-selling tool for crimping Cat5e and Cat 6 modular plugs for over 15 years. Precision ground crimp teeth and a steel-walled body keep the connector stable and all of 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.
