Harken
Harken 16 mm Hook-In Halyard Block
An ultralight Harken halyard block designed for hook-in halyard systems, where the sail's load is taken by the lock rather than the halyard once the sail is hoisted....
Halyard blocks built to carry the high static loads and constant use of hoisting. They run smoothly and reliably, reduce friction and make hoisting, dropping and tensioning your sails easier.
