The lightweight OK carabiner is made of aluminum. It has an oval shape that allows optimal loading of devices with a wide cross-section, such as pulleys, rope clamps and mobile fall arresters. Its fluid interior design and Keylock system facilitate handling.
It is available in three locking systems:
- TRIACT-LOCK: automatic locking with triple-action gate opening
- BALL-LOCK: automatic locking with triple-action gate opening, with lock indicator
- SCREW-LOCK: the manual screw-lock with red band provides a visual warning when the carabiner is unlocked
