The lightweight OK carabiner is made of aluminum with an oval shape for optimal loading of devices with wide cross-sections, such as pulleys and rope clamps. Its fluid interior design and Keylock system facilitate handling. Available with manual screw-lock, automatic TRIACT-LOCK, or BALL-LOCK systems. It connects to the CAPTIV bar to position the carabiner along the major axis, reducing flipping and keeping it integrated with the device.
