Wear and tear on the rope is reduced to the minimum thanks to the specially designed locking mechanism that lowers the fall arrest force (the force transferred to the body in the event of a fall) by half compared to other devices and locks the rope along a long axis, rather than pinching it aggressively with a toothed cam. Switching to the ascension mode is accomplished with the simple push of a button on the back of the device. The innovative cam also creates perfectly smooth action on the rope whether it is being used to ascend or descend the line. To be used on semi-static ropes ranging from 10 to 11 mm. The Goblin fall-arrester represents a monumental step forward in safety for workers who rely on fall arrest systems for work at heights. Brand CAMP Safety Gear 6059712
