Kernmantle Rope 12mm Anchor line complete with Rope GrabIn this system, the rope grab is constructed of high strength steel and works on a 12mm diameter kernmantle rope anchorage line, incorporated permanently on the anchorage line, and comes with an energy absorbing element. It is not detachable from the rope and this gives an advantage that the worker does not lose the device when the equipment is not in use. This system is an ideal fall restraint device for use while working on platforms and roofs.
