Profurl Racing Furling Extrusions are made lighter
and stronger by the use of special alloy (6106). These are aerofoil,
black anodised extrusions. Optimum torque resistance along
the entire foil length and the total absence
of play at the junctions avoid any possibility
of twist whilst
reefing. The foil shape is specifically designed for uniform rigidity
aerodynamic performance and smooth even rotation.
