What happened?
Unique Seaflex has identified the batch number of the parted master link. However, as these links are interchangeable, as a precaution, the company has decided to advise all owners or users of 10t air lift bags and 10t water load bags to inspect the master links fitted to their bags and quarantine any products marked with the following two possible lot numbers (which can be found embossed within the pressed section opposite the weld in the centre of one long side):
- IWA
- LWA
Members using 10t air lift bags or 10t water load bags fitted with a red master link marked IWA or LWA should contact Unique Group ([email protected]) for further information in regards to ring change-out and replacement instructions.
