Our chains with ring at one end have been conceived to be used as a belay system in multi-pitch routes as well as a rappel stance in speleo, canyonning and difficult descend walls. It is possible to clip any part of the unit with a carabiner which should always have a locking gate. The ring is placed perpendicularly to the wall so that it eases the retrieving of the rope. Available in D10 mm and D12 mm. Technical features Weight: 564 g. Strength: 25 Kn.
