From Norway Industries: Made with a blend of the strongest non-rubber materials available, DURAVANES have been designed and tested to outperform any other vane, (or feather) in all aspects.
Outstanding Features Tapered Blade - The blade on all DURAVANES has a slight taper from base to top for unbelievable size/weight versus steering power. This allows use of a much smaller vane than usual for a specific size shaft. This design also eliminates blade flap and unwanted noise. Suction Fit Base - Our base, fitting any shaft size, is specifically designed for an instant airtight surface-to-surface bond. Using DURALOC adhesive makes this bond indestructible.
NO Primer on Vane - Because our blend of materials requires no primer for adhesion, DURAVANES have unlimited shelf life.
