KFH4.5 external swivel lock compatible with KF4.5 series furlers or competing furlers of a similar size.

The KFH lock (or hook) is a 2-in-1 external lock and swivel. It is designed to replace the standard swivel (the upper part of the furling system) and is therefore used in combination with a furling drum to complete the system. The KFH V3 locks are Karver's latest generation of halyard locks, featuring an updated mechanism and silicon impact protection as standard.
