Heavy-duty boat fenders feature maximum resistance to breakage thanks to the two multiple solid ropes reinforced with arms. Tested for durability and flexibility at temperatures from -30°C to +50°C, they offer high abrasion resistance and high energy absorption (up to 3.8 tons for F-13). They are suitable for vessels up to 1500 tons (F-13) and are widely used by ferries, fishing boats, and commercial ships.
