The Petzl Bm’D lightweight asymmetrical carabiner is made of aluminium. It has a D shape particularly suited for connection to diverse equipment such as descenders or positioning lanyards. Its fluid interior design and Keylock system facilitate handling. This carabiner has the TRIACT-LOCK automatic locking system. The sleeve is reinforced for greater front and lateral gate strength. It may be used with a CAPTIV positioning bar to favour loading of the carabiner along the major axis, to limit the risk of it flipping and to keep it integrated with the device.
