Description

Low-friction Carbo Air blocks are lightweight, strong, reliable, and affordable. Companions to our popular Harken Big Boat blocks, 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. 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, sheaves, and side plates are UV-stabilized with carbon-black additives for maximum protection.
