In order to ensure that you get the perfect product for your unique application we offer our D fenders in a choice of different formats, with each offering their own strengths.

DD Fenders

These fenders are well known from the D shape of the fender and the D shape of the inner hole. DD type fenders are some of the most common format of fenders which are widely used all over the world. The D fenders are drilled straight down through the centre in order to bolt the fender to the desired surfaces. They can also drilled through the fender base to be installed to the required surfaces

DO or DC Fenders

DO type fenders are also called DC fenders. they are similar in design to DD fenders. However, these fenders highlight a round shaped hole running through them. These typical fenders are drilled through the base, which enables you to bolt the fender into a channel. This makes them popular for use directly on sea vessels for docking protection.
