CAMP Goblin Fall Arrester 26cm Trilock Kit To be used on semi-static ropes ranging from 10 to 11 mm. Performance can be further increased by using the new patented Rope Surfer device. Switching to the ascension mode is accomplished with the simple push of a button on the back of the device. Certified for single use up to 120 kg and for double person rescue scenarios up to 200 kg. 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.
