Low-friction Harken Carbo Air blocks are lightweight, strong, and reliably affordable, built as a companion line to Harken’s popular Black Magic blocks with very high working loads for their size.
The fixed (non-swiveling) mount is the right call when the block’s lead angle stays constant, saving the weight and complexity of a swivel that isn’t needed.
Rated to a 970-lb maximum working load, it’s built for safe, easy trimming without adding unnecessary weight to the rig. Check out the rest of our sailing hardware.
