The Am’D lightweight asymmetrical carabiner is made of aluminum. It has a D shape particularly suited for connecting to diverse equipment such as descenders or positioning lanyards. Its fluid interior design and Keylock system facilitate handling. The Am’D carabiner is available in three locking systems: automatic TRIACT-LOCK or BALL-LOCK system, or manual SCREW-LOCK system. Am’D may be used with a CAPTIV positioning bar to promote loading of the carabiner along the major axis, to limit the risk of rotation, and to keep it integrated with the device.
