Lesson 1Climbing hardware and connectors: carabiners, rope rings, lanyards, cambium savers, friction devices, ascenders, descendersDetails key climbing hardware used in arboriculture here in Eritrea, including carabiners, rings, lanyards, friction devices, ascenders, and descenders. Emphasizes ratings, compatibility, inspection, and correct orientation to prevent failures in tough conditions.
