I had my shipment of Norselay sent to me in Whangarei about 6 years ago. The contact at Brunton Shaw in the UK was Phillip Matthews. Very cooperative; sorry you are having trouble. How will you terminate the wires?
Also NOT virtually indestructable. Take care to avoid side loads and wear spots on the poly cover. I added terminals at the spreaders to avoid this problem. I also have 8mm Norselay for my lifelines
and some of the poly is wearing through where they go through the stantions. However it is repairable with a small blow torch you can "weld" the damaged area, so save the poly pieces you cut off the ends to terminate the wires. Any more tips? Let me know.
