The light and asymmetrical Bm'D carabiner is made of aluminium. It has a D-shape particularly suitable for connecting various devices such as descenders or positioning lanyards. The fluid interior design and the Keylock system facilitate handling. The Bm'D carabiner is equipped with the TRIACT-LOCK automatic locking system. The ring is reinforced for better frontal and lateral resistance of the finger. Bm'D can be combined with the CAPTIV bar to encourage loading of the carabiner along the major axis, limit the risk of it rolling over and secure it to the device.
