HARKEN 75mm Carbo Block - Swivel, Becket, Cam Cleat, 2667

Low-friction Carbo Air blocks are lightweight, strong, reliable, and affordable. Companions to our popular Harken Big Boat blocks, these small, compact blocks have very high working loads for safe, easy trimming.

Carbo AirBlocks® are 60% stronger and 30% lighter than Harken's classic series, designed especially for the racer looking for higher strength to lower weight ratios. Use for main/jib sheets, mainsheet fine-tuning, control lines, vangs, Cunninghams, outhauls, etc.

Note: Special Order Only

• Long fiber, glass-reinforced nylon resin sideplates
• Ball bearings, sheave, and sideplates are UV stabilized for maximum protection
• Cam-Lock or U-Lock locking systems to lock the shackle in front or side positions, or swivel to keep the line from twisting
• Cams release easily under load - perfect for mainsheet systems on sport boats like Melges 24s, J/105s, and Henderson 30s
• Breaking load is 3 times the safe working load, except single blocks w/cam is 2.5 times SWL
• Note: for blocks equipped with cams SWL and BL are based on cam strengths
