Hi Steve
Thanks for the info. We have sent it to the mast factory to see what they say, and are awaiting an answer.
I must say that we had no failure on the collar on the Severne Red Line mast's here at the R+D in Perth over the last 4 years.
Can you please take some picture of your collar? - And send it to
jesper_naturalcorp@bigpond.com
Thanks
