Large diameter coaxial cables such as the LMR®-400, LMR®-600, WBC-400 and WBC-600 require heavy duty crimping tools. The RFA-4009-20 cushion gripped crimp handle weighs 1.3 pounds, and is designed to deliver piston-driven compression for installation of crimp ferrules on large diameter cables. For safety and efficiency, the ratchet mechanism is designed to release after the ferrule is completely crimped. Two die sets are available for use with this crimp handle: the RFA-4009-01 has a .610 inches hex cavity for use with .600 inches diameter cable; and the RFA-4009-02 is designed for use with .400 inches diameter cable with a .429 inches hex cavity for ferrules and a .118 inches hex cavity for contacts. The RFA-4009 kit contains the RFA-4009-20 handle and both the RFA-4009-01 and RFA-4009-02 die sets packaged together in a foam lined, sturdy, plastic case with expansion slots to accommodate four additional die sets.
