HARKEN 2604 

Triple Carbo AirBlock® - 57mm

Low-friction Carbo AirBlocks® are lightweight, strong, reliable, and affordable.

Carbo AirBlocks® 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. Ball bearings, sheave and side plates are UV-stabilized with carbon-black additive for maximum protection.

Blocks feature Cam-Lock or U-Lock locking systems to lock the shackle in front or side positions, or swivel to keep line from twisting. The high-load 57mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24's, and for mainsheet systems on catamarans.

Like all AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single Allen® wrench.

Use for:
  • Main/jib sheets
  • Mainsheet fine-tune
  • Control lines
  • Vangs
  • Cunninghams
  • Outhauls

Specifications:
  • Sheave Diameter - 57mm (2-1/4")
  • Max Line Diameter - 7/16" (10mm)
