The 59824-1 is a Tetra Hand Crimp Tool designed to crimp the terminals and splices onto stranded wire sizes 22 through 10AWG. Each hand tool features two crimping dies, a spring-loaded locator assembly and a ratchet handle with a ratchet pawl. When closed, the dies form three crimping chambers each labeled by color on the back side of the tool. The color indicates the wire size and must match the insulation color of the terminal or splice: yellow (12-10), blue (16-14), red (22-16), black heavy duty (16-14 HD) and green (20-16 HD). The locator assembly positions the terminal or splice between the crimping dies. The ratchet handle assures full crimping. Once engaged, the ratchet will not release until the tool handles have been fully closed, unless the ratchet pawl is depressed to manually release the ratchet. This feature, when depressed, prevents crimping of an improperly positioned terminal or splice.
