The chain grabber is safe, designed to be as strong as high test chain.
Ideal for use with a snubber or a bridle.

The safety factor we use to determine the safe working load is 4, where other manufacturers use the safety factor of 3 or lower thus UBS is the best way to compare strength between products.

The material properties of the carbon steel we use when manufacturing galvanized steel hook are the very similar to 316 stainless steel, thus the WLL and UBS values are practically the same for the galvanized and stainless steel hooks.
