The 384 vang block features high-load composite bearings to handle wire and high-strength line.
Use it with the #382 Radial Car (or other Harken Small Boat cars) to configure a very low profile radial boom vang, only.
Do not use this block on a mainsheet traveler.
The 384 vang block sits recessed into the car to help prevent block-to-block vanging. (Remove the shackle that comes with the #382 car.)
Please refer to this Harken Star Deck Layout for more information about how this block is used.
