The stopper is crafted using advanced lightweight materials. The molded parts, DO 550, are constructed from high-quality plastic, offering both durability and impact resistance while remaining lightweight. For enhanced performance in the marine environment, the cams and bases are made of marine aluminum, anodized to ensure a long lifespan.
The stopper's design incorporates specially hardened teeth, providing maximum grip with minimal slippage and being gentle on the ropes. Releasing under load is effortless, requiring minimal effort. The mechanism's opening and closing action is precise and user-friendly, even in cold and wet conditions, with a positive handle block in the closed position.
To minimize wear and friction on the ropes, stainless steel cable glands are installed at both the entry and exit points. Additionally, the DO 550 range of clutches is designed with a bolt-on construction, making maintenance and parts replacement simple and hassle-free.
