Yellow Monopile Donut Fender Low Reaction Floating Foam Fenders Marine
Donut Foam Fenders are an effective solution for simple berthing dolphins, guide structures and turning structures. The buoyant Donut Fenders floats up and down a single tubular pile and freely rotates to help align or redirect ships. The internal casing has long lasting, low-friction bearings that need minimal maintenance. The foam is unsinkable and cannot burst or deflate. The Donut Fender skin is durable polyurethane reinforced with continuous nylon filaments.
Donut Foam Fenders are custom-designed for every application. They have supplementary buoyancy to present a raised contact face. The donut fender body can be additionally protected with a thicker skin or wear strips to cope with ferry beltings. Bright colors are often used to improve visibility and safety. A variety of applications include corner protection, turning structures, lead-in jetties, simple breasting dolphins and bridge protection.
