The Chain Hook, or chain grabber securely latches to the chain even when chain is unloaded, making it much safer than standard chain hooks that often fall off.

The Hook is made from 2205 Duplex, thus withstanding the harsh marine environment and is the strongest hook on the market.

The chain grabber is safe, designed to be as strong as high test chain.

Ideal for use with a snubber or a bridle.

Fits BBB, Proofcoil, Hi Test and Stainless Chain.

Available for 1/4, 5/16, 3/8, and 1/2 inch chain.

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 galvanised steel hook are the very similar to 316 stainless steel, thus the WLL and UBS values are practically the same for the galvanised and stainless steel hooks.
