Shackles make excellent secure, metal to metal and metal to fibre (rope, webbing) connections in the marine environment - multiple uses for attachment generally onboard together with significant mooring/anchoring applications.

There are various options and permutations:

  • Hot Dipped Galvanised or Marine Grade Stainless Steel
  • Rated or unrated
  • With manufacturer certificate or without
  • Dee or Bow shape with extra options - Long Dee, Wide Dee, Twisted Dee
  • Standard Pin (protruding twist grip) - Socket Pin (flush fitting) - Shakeproof pin (flush fitting) - Allen Head Pin (flush fitting)

Select the appropriate shackle for your intended use:
  • It is advisable to avoid connecting dissimilar metals, although there are exceptions which are explained in Stainless in contact with Galvanised
  • Choose a manufacturer load rated shackle with test certificate for all load critical applications 
  • Select the Dee shape as standard unless the extra articulation offered by the Bow shape is required
  • Select Standard Pin unless the more streamlined flush fitting pin is required to avoid snagging

Shackle Tools and Accessories
It is useful to have a shackle key and a marlin spike in the onboard tool or rigging kit for tightening and unfastening stubborn shackle pins.

Seizing wire and Loctite are also handy additions to your onboard maintenance arsenal -
Critical shackles, especially those that are not easily checked on a regular basis should have the thread locked with an additive such as Loctite and the shackle pin head seized with Monel Wire
