External halyard lock (installed with a lashing on the fore of the mast) dedicated to front sails being furled with a continuous line furler (staysail, code sails, asym …).

In a unique product, we have combined a lock and a top swivel. Using a KFH makes it possible to no longer have the halyard under load at all time. The lock eliminate the inconvenient of the halyards stretching.

For the past 10 years, the KFH furling lock has been the most optimized lock on the market. 80% of the Imoca fleet is using it!
