The FRONT of the tool, is marked with the tool part number, wire size ranges, and crimp height Specifications. The tool features a fixed die (crimper), a movable die (anvil), a locator/insulation stop, and a ratchet. Many tools feature an insulation adjustment knob which is used to regulate the crimp height of the contact insulation barrel during the crimping operation. The locator/insulation stop positions the contact, and limits the insertion distance of the stripped wire into the contact. In use, the locator/insulation stop rests in the locator slot of the contact (See Figures 1 and 2). The ratchet assures full crimping of the contact. Once engaged, the ratchet will not release until the dies have been fully closed.
