HARKEN 2640

Triple 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.

Use for:

Main/jib sheets
Mainsheet fine-tune
Control lines
Vangs
Cunninghams
Outhauls
