Harken 2652 40mm Single Carbo Airblock Fixed Stand-Up Block

HARKEN 2652 

Single Stand-Up Carbo AirBlock®

Stand-Up Fixed - 40mm

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 the 40mm Carbo (No. 2652) for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats.

Use for:

• Main/jib sheets
• Mainsheet fine-tune
• Control lines
• Flag halyards
