40MM SINGLE CARBO AIR BLOCK W/SWIVEL

The Harken 40mm Carbo Air Block with Swivel is a lightweight, low-friction pulley built for smooth line handling in compact rigging setups. With a larger 40mm sheave and higher working load than the 29mm version, this block is a strong option for outrigger rigging, dredge pulley setups, teaser systems, control lines, and other custom marine applications.

The swivel head helps the block align naturally under load, reducing twist and keeping line movement clean. Harken’s Carbo Air construction keeps the block light while still providing dependable strength for demanding use on the water.
