Abstract
Abstract The tool includes a housing and a pair of forwardly projecting tubes respectively containing slidably mounted rods, one for use in tensioning a lock wire and the other for use in crimping a ferrule onto the lock wire. Camming structure moves the rods forwardly and rearwardly. First, the tensioning rod snaps back under the control of a spring to tension the wire. Then, the ferrule is crimped by forward movement of the other rod.
