Boat fenders feature maximum resistance to breakage through two multiple solid ropes reinforced with arms. They are tested for durability and flexibility at temperatures from -30°C to +50°C. These heavy-duty fenders provide high abrasion resistance and high energy absorption (up to 3.8 tons for F-13), making them suitable for vessels up to 1500 tons (F-13). They are widely used by ferry boats, fishing vessels, and commercial ships.
