This alert was originally issued for European and Australian tower workers by The Construction, Forestry, Mining and Energy Union (CFMEU), Australia’s main trade union in building and construction, forestry and furnishing products and mining and energy production. Tower workers in the U.S. have recently become familiar with the knock-offs.

    • Purpose: To raise awareness of potential counterfeit Crosby shackles and the consequences of their use.
  • Description: Counterfeit Crosby Shackles have been found at locations in Europe. These shackles are NOT up to required standards and it is mandatory that they be immediately removed from service. The counterfeit shackles can fail at as low as just 40% of their stated rating, causing a potentially catastrophic outcome. The most obvious difference is that the counterfeit shackle has the word “CROSBY” all in capital (Upper Case) lettering. The genuine shackle only has the “C” of “Crosby” capitalized.


The points to look for in deciding whether you have a Crosby shackle or a copy are:

  • On the face, (a) the Crosby Name should be embossed as per the Crosby Logo, (b) the CE mark should appear along with the (c) markings of the 45 degree angles
  • On the rear of the shackle should appear 2 different groupings of IDs (3 for Belgium manufacture) providing full traceability of the shackle.
  • The pin should also be stamped (d) on the head with a tractable ID number.
