Death Diamond Drowner Locks are constructed of 3/16" steel, so you don't have worry about the strength of this product. These are the strongest drowner locks on the market. The diamond opening on the drowner is compatible with any sort of material but really performs well on long rods of fiberglass or carbon fiber.
