Wing D Fenders are developed on the basis of D Fenders. They can be fixed with double line anchors which greatly increase the installation stability. Furthermore, their anchoring bolt is bigger than D Fender so that the anchoring grip is double to D Fender. Usually wing D fenders are used as an alternative to other profiles as beltings for tugs and workboats. Instead of drilling the fender, the wings of wing D fender are retained by steel angles.
