Harken 2659 40mm Single Carbo Air Fixed 90° Block
HARKEN 2659
Single Fixed Carbo AirBlock® - 40mm
Sheave Diameter 1-9/16"
Low-friction Carbo AirBlocks® are lightweight, strong, reliable, and affordable.
Carbo AirBlocks® 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 sideplates are UV-stabilized with carbon-black additive for maximum protection.
Use the 40mm Carbo for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats.
Like all AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single Allen® wrench.
