Harken 75mm Swivel Triple Carbo Airblock w/ Becket

Harken's Carbo AirBlocks® are 60% stronger and 30% lighter than Classic blocks.  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-stablized for maximum protection.

The high-load 75mm Carbo releases easily under load and is perfect for mainsheet systems on sport boats like the Melges 24, J/105, or Henderson 30.  Other uses include mainsheet fine-tune, control lines, vangs, cunninghams, and outhauls.

Swivel blocks can lock in two directions or spin freely to avoid lines twisting.
