Description SilverLine® Armored TuffGrip Test Cable, 3.0 Meter, 6GHz, NM/NFG. TuffGrip® employs a hefty handgrip at the system end to better withstand the rigors of field work. It meets the demands of repeated mating and unmating to cell tower cables with connectors that may have degraded from exposure. The robust hand grip allows the user to apply as much resistance as necessary to properly torque the system cable connector, while preventing excess torque from being applied to the high performance test cable. A proper connection may now be made quickly with a single wrench. TuffGrip® test cables are double steel armored and antitorqueing, yet they are completely flexible. All connectors are stainless steel for thousands of mating cycles.
