HellermannTyton Mark 9 - a handheld pneumatic tool that will tension and cut cable ties with tensile strengths ranging from 50-250 lbs. This military grade tool features a lightweight and ergonomic design with an impact resistant housing and rugged chromium steel components to provide durability. A knob and display ensure ease of tension adjustments. The Mark 9 offers the same design features as HellermannTyton’s MK 7, but is built to handle heavy duty ties. The Mark 9 can be used with almost every cable tie manufactured by HellermannTyton, including the T18 and T250 series, as well as Wide Strap and EL-TY ties.
