RotafenderTM-180

This fender system is designed for pier impact protection that minimizes the force transmitted to the structure, being capable to absorb the energy with higher displacement and less reaction force. The fender is a flexible type made of Butyl Elastomer and EPDM which is highly resistant to the environment and has mechanical properties with a high degree of elasticity and resistance.

Its mechanics allows it to freely rotate in its support axle thus reducing the forces transmitted along the vessel.

It is an integral design that allows it to be installed along the splash zone without any changes to the structure.
