Harken 29mm Single Swivel Carbo Block (HK340)

The compact 29mm Carbo is extremely strong. Use our miniature Carbo as a mainsheet block on small dinghies such as the Optimist, or for low-friction control blocks on any size boat.

Doubles and triples feature U-Locks to hold the swivel in front/side position, or to let it spin freely. The triple's compact cam arm supports high-load purchases of 5:1 or 6:1

The line-shedding cheek block features a small mounting footprint and drainholes. The low-profile Ti-Lite replaces the headpost, shackle, and spring with high-tech line.
