Harken 40mm Carbo Blocks
Carbo AirBlocks® are 60% stronger
and 30% lighter than our Classic blocks. Use the 40 mm Carbo for jib
and mainsheet systems on high-performance 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.
