Donut Fender
Lightweight and durable, Donut Fenders are perfect for small vessels and temporary mooring.
The ocean guard Donut fender is a specific type of Foam Fender. It is designed to simply slip over a stationary monopile. Due to its construction, the fender floats up and down with the fluctuating water levels and rotates when vessels berth and slide along the fender. The Donut Fender is designed with a 100% closed-cell cross-linked polyethylene foam core, a reinforced elastomeric skin, and low friction pads at the internal steel core.
Donut Fenders are available in diameters from 1,270 mm to 4,220 mm and a maximum pile diameter of 610 mm to 2,388 mm. Additionally, mooring crowns, counterweights (for sub-marine applications), or other features like protective nettings can be added.
