External halyard lock (installed with a lashing on the fore of the mast) dedicated to front sails not being furled such as the genoa or fixed staysail. We also offer this locking solution as an addition to our structural furlers. As opposed to the external furling lock KFH, the KHL is not integrating a swivel. Using a KHL makes it possible to no longer have the halyard under load at all time. The lock eliminate the inconvenient of the halyards stretching.
