Antal 150mm Clew Block
features anodized aluminum cheekplates and guarantees the least weight
as well as a very good mechanical resistance to the environment. The block
is designed to solve the connection of a sheave to the furling mainsail clew
efficiently, while containing the block within the size of the sail, allowing
for a larger surface of the mainsail to be used. Particular care has been
taken over the ease of connection by webbing, ensuring a very good
distribution of the load on the sail.
