Harken 29mm Carbo Blocks

The compact 29 mm Carbo block is extremely strong. Use Harken's 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.

Use for:

  • Outhauls
  • Cunninghams
  • Vangs
  • Traveler controls
  • Barberhaulers
  • Flag halyards
