Rubber fenders are essential for protecting docks, ships, and marine structures from collision damage. But simply buying a fender is not enough—you need the right accessories to install them safely and securely. Whether you’re outfitting a busy commercial port or a private marina, understanding the required accessories is key to long-term performance.
Why This Matters: Real-World Consequences
Imagine installing a rubber fender without a proper chain system or using the wrong bolts. Under pressure, the entire unit might shift or detach, putting ships and infrastructure at risk. At Sunhelm, we’ve seen how poor installation choices can lead to expensive repairs. That’s why this guide is so important—we want you to get it right the first time.
Essential Accessories for Rubber Fender Installation
1. Anchor Bolts and Base Fasteners
You’ll need heavy-duty anchor bolts, U-anchors, or chemical anchors to fix the fender to the dock wall. These fasteners ensure the fender stays in place even under repeated impact.
Pro Tip: Always use marine-grade stainless steel to resist corrosion.
2. Mounting Plates and Brackets
Depending on the fender type (D, arch, cone, or cell), mounting plates or custom brackets may be required to distribute pressure and provide a flat surface.
3. Chains and Shackles
Most rubber fenders—especially cone and cell types—rely on chain systems for performance and safety:
Tension chains for absorbing pulling forces
Shear chains for sideways movement control
Weight chains for vertical balance
You’ll also need shackles, turnbuckles, and chain tensioners to secure and adjust these systems.
4. Sealing and Bonding Materials
Use marine sealants and structural adhesives to waterproof bolt holes and glue base plates. In chemical anchor systems, epoxy or resin injectors are also necessary.
Tools You’ll Likely Need
Hammer drill and concrete bits
Wrenches, socket sets, torque tools
Caulking gun, level meter
PPE (gloves, safety goggles, dust mask)
Installation Steps in Brief
Measure & Mark positions for the fenders based on design specs.
Drill Holes using appropriate bits and tools.
Install Anchor Bolts or chemical anchors, allowing curing if needed.
Mount Fenders and Panels, ensuring correct alignment.
Tighten All Chains and Bolts, using tensioners where applicable.
Seal All Gaps with marine sealant to prevent corrosion.
FAQ
Q1: Can I install rubber fenders without chains? A: No. Chains are critical for controlling the movement and energy absorption of larger fenders like cone and cell types.
Q2: What tools are essential for fender installation? A: You’ll need drills, torque wrenches, chain tensioners, and safety gear like gloves and goggles.
Q3: What’s the function of a UHMW-PE panel? A: It reduces surface friction and prevents direct contact between the rubber and ship hull, minimizing damage.
Q4: Does fender size affect accessory selection? A: Yes. Larger fenders typically require more robust anchoring systems and complete chain assemblies.
