Harken Carbo AirBlocks
Harken Carbo AirBlocks are
60% Stronger and 30% lighter than the Classic Blocks.
Use the Harken 40 mm Carbo Block for jib and mainsheet systems
dinghies and for loaded control lines on small keelboats.
The nylon-resin sideplates 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 sideplates
are UV-stabilized with carbon black for maximum protection.
High-Strenghtpivoting lead blocks with cams are used for halyard controls on larger keelboats and as "head knockers" on dinghies and beachcats for sheeting directly rom the boom. Hole spacingand rivet size are the same as Classic models, making upgrades easy. Cam reverses for either up or down cleating.
