29mm Carbo
Clew Block Assembly


Harken 371
The 29 mm Carbo block is like jewelry. This compact block is extremely strong. Use the 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 headpost, shackle, and spring with high-tech line.

Use for:
  • Outhauls
  • Cunninghams
  • Vangs
  • Traveler controls
  • Barberhaulers
  • Flag halyards
