The lightweight WILLIAM large-capacity asymmetrical carabiner is made of aluminum. The pear shape makes it easy to attach multiple items. Its fluid interior design and Keylock system facilitate handling. The WILLIAM carabiner is available in three locking systems: automatic TRIACT-LOCK or BALL-LOCK, or manual SCREW-LOCK. WILLIAM can be used with the CAPTIV bar to promote positioning of the carabiner along the major axis, to limit the risk of rotation, and to keep it integrated with the device.
