Product Description

Engineering detail & application context.

JettyGuard’s DD Fenders are high-performance rubber profiles engineered for versatile impact protection in demanding marine environments. Their unique ‘D’ shape provides a broad, flat contact face for effective energy absorption while being easy to mount on both flat and curved surfaces. Manufactured from premium, marine-grade EPDM rubber, they offer superior resistance to abrasion, UV radiation, and seawater, ensuring a long service life.

Key Advantages

  • Versatile Profile: The D-shape is ideal for a wide range of applications, providing excellent protection for vessels like tugs and workboats, as well as structures like small jetties and pontoons.
  • Simple Installation: DD Fenders can be easily and securely installed by bolting directly to the hull or quay wall. They can be supplied in specific lengths and pre-drilled to match your project requirements.
  • Durable EPDM Rubber: Our EPDM rubber compound is non-marking and exceptionally resistant to environmental degradation, providing consistent performance without requiring significant maintenance.
  • Reliable Protection: Despite their simple profile, DD fenders effectively absorb berthing energy, protecting both the vessel and the docking structure from costly impact damage during mooring and maneuvering.

Ideal for moderate-duty fendering, these profiles are a go-to solution for pilot boats, barges, and wharf protection. Available with a hollow D-shaped bore or solid core, our DD Fenders can be customized to meet the specific energy absorption and reaction force needs of your operation. Trust JettyGuard for a robust and economical fendering system.
