We are considered as a specialist in offering the best quality range of Cable Tie Tool MK 9. Specifically developed for maximum ergonomic and performance values, the Mark 7 and Mark 9 series tools combine reduced hand effort and durable components to ensure efficient assembly and a longer life cycle. The Mark 7 tools are used with T18 through T50 series Hellermann Tyton cable ties. The Mark 9 tools can be used with nearly every Hellermann Tyton cable tie. Able to accommodate ties to .530" in width, the Mark 9 is used with Hellermann Tyton\'s T18* series cable ties to the heavy duty ties, including the T250 series and EL-TY. High tension versions of both the Mark 9 and Mark 7 tools (MK9HT and MK7HT) offer the same design features as their standard counterparts but with higher cut-off tension capabilities. The Mark 9 and Mark 7 high tension tools both offer a 5/8" stroke.
