The Tylaska Cone fid allows for remote release of the Tylaska trigger shackles. A lanyard is placed through the center hole of the fid with a retaining screw to lock the lanyard in place. The fid is set up with the lanyard running through the trigger of the snap shackle where it remains loose. When the lanyard is pulled, the fid engages the trigger, releasing the shackle. The double cone fid is designed to go through the trigger area and separate from the shackle. The single cone version is designed to stay in the trigger area and remain with the shackle. These fids are ideal for avoiding the need to crawl out into risky locations, for single handed or night sailing. The CF20 is designed specifically for use with the Tylaska T20 Snap shackle
