Movable die (anvil) and two fixed dies (crimpers) - crimp the connectors. Two wire supports - position and hold the wires in the crimpers. Wire cutter - performs two functions. First, it locates the connector on the anvil, and second, it cuts excess wire during the crimp cycle. Moving handle (with quick-take-up lever and CERTI-CRIMP ratchet) - pushes connector into crimping dies and ensures a highly uniform, finished connection every crimp cycle. Fixed handle - provides support during crimp cycle and, when applicable, can be held securely in tool holder.
