  • The Mantus Chain Hook has no moving parts, thus can withstand harsh marine environment
  • The chain grabber is safe, designed to be as strong as high test chain
  • The Mantus Hook will work with your bridle, snubber, or can join two chain strands
  • 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 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.

These strength ratings are lower then previously reported: see why here

Shackles are now included with the hooks
