Harken 349 29mm Single Carbo Air Fixed Sailboat Stand-Up Block
HARKEN 349
Carbo AirBlocks®
Stand-Up Fixed - 29
Carbo AirBlocks® are extremely strong and compact. They are 60% stronger and 30% lighter than Harken's Classic blocks. The Nylon-resin side plates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Sheaves spin on high-load ball bearings with fitted races for low-friction operation. Ball bearings, sheave and side plates are UV-stabilized with carbon-black additive for maximum protection.
Use Harken's miniature Carbo (No. 349) as a mainsheet block on small dinghies such as the Optimist or Sabot, or for low-friction control blocks on any size boat.
Use for:
- Main/jib sheets
- Mainsheet fine-tune
- Control lines
- Flag halyards
