INTENDED USE: The DJINN STEEL carabiner is designed for intensive use in climbing gyms or for working routes at the crag. SIZE AND STRENGTH: This large carabiner (27 mm gate) has a major axis strength of 28 kN. EASY TO USE: The large gate opening makes it easy to manipulate the carabiner while the wider contact surface offers better glide and less wear. MORE DURABLE: The steel construction offers greater durability while the aluminum gate offers the same clipping feel as the DJINN. NO MORE SNAGGING: Petzl's Keylock system helps avoid accidentally snagging your carabiner on your gear.
