Harken Blocks

Harken 75mm Carbo Blocks

The 75 mm Carbo has a safe working load of 1200 lbs (500 kg).  It releases easily under load and is perfect for mainsheet systems on sport boats like the Melges 24, J/105, and Henderson 30.

The nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio.  Ball bearings, sheave, and sideplates are UV-stabilized with carbon black 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.

Use for:

  • Main/jib sheets

  • Mainsheet fine-tune

  • Control lines

  • Vangs

  • Cunninghams

  • Outhauls
