The JEMLINE 325ZL is similar to the Model 325 except it features the Z-Lock reverse safety notch. Application of the Z-Lock handle punches a safety notch into the strapping that prevents movement of the crimping joint and virtually eliminates the possibility of the crimped joint pushing apart when not under tension. The tool is available to handle 1/2"(13mm), 5/8"(16mm), and 3/4"(19mm) up to .25(0635mm) Hi Tensile strapping.
