M2 Chain Hook


  • The M2 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 M2 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.
