Carbo AirBlocks® - 29mm
These compact blocks are extremely strong, as well as lightweight, reliable and affordable. Use Harken's miniature Carbo as a mainsheet block on small dinghies, such as the Optimist or Sabot, 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 low-profile Ti-Lite replaces headpost, shackle and spring with high-tech line.
