Lightweight asymmetric big karabiner available in Screwgate, Twistlock, Ball Lock and Black Screwgate or Twistlock for tactical.

The lightweight WILLIAM large-capacity asymmetric carabiner is made of aluminum. It has a pear shape that is practical for easily connecting multiple items. Its fluid interior design and Keylock system facilitate handling. The WILLIAM carabiner is available in three locking systems: automatic TRIACT-LOCK (this is also known sometimes as  a 'Twistlock') or BALL-LOCK system, or the manual screwgate system.
