Cylindrical Rubber-Dock Fender is a type of solid fender with hollow inside diameter in proportionate with the outer diameter. Generally, the standard proportion / ratios between the outside diameters and the inside diameters are 2:1 and 1.75 :1. The cylindrical fender is used to clamp upon the quay / jetty for absorbing the shock or impact created by rubbing of the steel of a vessel with the quay .The hollow inside the fender acts as a spring which gives cushioning effect and the load/shock is dispersed all over the fender, thus protecting the quay and the vessel's body.

Besides, cylindrical fender can be installed at the bow of the vessel to be hung horizontally along with chains on either sides.
