The 220015-1 is a heavy head hand Crimp Tool for use with AMP coaxial connectors. It features integral dies that have two crimping areas (one to crimp the center contact and one to crimp the ferrule), an adjustment cap that rotates the locator-stop (as required) and a CERTI-CRIMP hand crimping tool ratchet control which ensures full crimping. Once engaged, the ratchet will not release until the tool handles have been fully closed. This crimp tool is intended for occasional use and low volume applications.
