High strength, large capacity asymmetric carabiner VULCAN is a high strength steel carabiner intended for use in harsh environments. The asymmetrical shape of large capacity is suitable for the realization of multiple moorings. The VULCAN carabiner is available in two locking systems: automatic TRIACT-LOCK system and manual SCREW-LOCK system. VULCAN TRIACT-LOCK is available in European and international versions. VULCAN can be associated with the CAPTIV bar to promote the bias of the carabiner along the major axis, limit the risk of overturning and secure it to the device.
