The FREINO is a great locking harness biner for anyone who makes long rappels on rock, in caves, while canyoneering or on rescues. The additional wire-gate captive hook (12 mm clearance) increases your rigging options and adds friction by changing the ropes departure angle and path. Smooth Keylock design with Twist Lock gate (15 mm clearance) avoids unwanted snagging on harness belay loop. Can be used with the SIMPLE, STOP, GRIGRI or other device.
