Harken 40mm Carbo Cheek Block

Harken 40mm Carbo Cheek Block

Low-friction Carbo AirBlocks® are lightweight, strong, reliable—and affordable. Companions to the popular Harken® Black Magic® line, these small, compact blocks have very high working loads for safe, easy trimming.

Carbo AirBlocks® are 60% stronger and 30% lighter than Harken’s Classic blocks. Use the 40 mm Carbo for jib and main sheet systems on high-performance dinghies and for loaded control lines on small keelboats.

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 for maximum protection.
