The slightly asymmetric Am'D carabiners are made of aluminum. Its D-shape is ideal for attaching various devices (descenders or lanyards for work positioning). The edge-free surface on the inside and the keylock system make it easy to attach and detach. The Am'D carabiners are available with three locking systems: the automatic TRIACT-LOCK and BALL-LOCK systems and the manual SCREW-LOCK system. The Am'D can be combined with the CAPTIV positioning bar to favor the loading of the carabiners in the longitudinal axis, prevent twisting and ensure that it forms a fixed unit with the device.
