HAL-LOCK eliminates the need to tie the outrigger halyards together with rubber bands or wire, or using a sliding swivel arrangement. I think most would agree that reaching out over the side of the boat with both hands tying halyards together is not the safest place to be in rough seas.
The HAL-LOCK outrigger pulley was specially designed for speed and efficiency (and it looks good too). Simply pull the locking lever back and the halyard is pushed into the softer urethane insert locking the halyard in place. That Easy! That Fast!, and because of HAL-LOCK’s unique ability to lock, very little tension is required on the shock cord, allowing you to get your clip up and back down with less effort.
