According to the installation methods,DC-type rubber fenders are divided into side hole mounted fenders and up and bottom hole mounted DC-type fenders.

With reasonable reaction force it may absorb more energy than that of cylindrical type.
Convenient in mounting.
lt is usually used for dock of frame work type and ships due to the small size of its bottom width.
Hybrid Design, Superior Performance: Merges the stable, flat-back mounting of a D type fender with the high-energy absorption profile of a cylindrical fender.
Excellent Energy Absorption: Absorbs more impact energy than a standard cylindrical fender of similar size, providing better protection for your dock and vessels.
Convenient & Easy Installation: The flat back allows for straightforward mounting on both dock walls and vessel hulls, reducing installation time and cost.
Space-Efficient Design: Its compact bottom width makes it perfect for frame-type docks and various ships where space is a constraint.
Durable & Long-Lasting: Manufactured by Tonly with high-quality rubber compounds to withstand harsh marine environments.
The DC-type fender is an evolution in marine engineering, designed to solve the limitations of traditional shapes:
Higher Energy/Reaction Ratio: Unlike standard D-type fenders, the DC-type's cylindrical front allows it to absorb significantly more energy while maintaining a reasonable reaction force.
Superior Mounting Stability: Compared to Cylindrical fenders, the DC-type features a flat base that prevents rotation and simplifies installation on frame-work docks.
Space-Efficient Geometry: Its narrower base width makes it the perfect solution for vessel sides and docks where mounting space is restricted, but high protection is required.
"DC" stands for D-Cylindrical hybrid. This innovative design ingeniously integrates the flat-back mounting stability of a D-type fender with the curved, high-energy-absorbing face of a cylindrical fender. It provides a superior protection profile for diverse marine environments.
The choice depends on your specific application. Up-and-bottom hole mounting is typically engineered for permanent, heavy-duty dock installations where maximum shear resistance is needed. Side hole mounting (often referred to as DD-style) is frequently preferred for vessel and boat protection, as it allows for easier bolt access and simplified maintenance.
Absolutely. Due to its compact bottom width and optimized energy absorption, the DC-type fender is an excellent solution for the side fendering of tugboats, workboats, and pontoons. It offers the heavy-duty cushioning needed during frequent berthing operations without occupying excessive space.
With a more reasonable reaction force, the DC-type can absorb significantly more kinetic energy than a cylindrical fender of similar dimensions. Its flat base also ensures it won't roll or shift under pressure, providing a more stable contact point.
