Product Overview Cone Fenders Construction: Leg Fenders are moulded into a rhomboid shape for optimum energy absorption. The twin notches on the side of the fender ensure it will compress at exactly the same point on each compression. These fenders can be combined with additional legs to form either a simple V-fender, or a larger and more sophisticated Modular Fender system. They can be mounted ver tically or horizontally on any quay wall. Construction: DockGuard Cone Fenders offer the most advanced cone fender technology available. Energy/Technical: The normal compression on a leg fender is...
