G'day Mac,
I'm in the market for a packed section and after finding the post where you mention the aproximate amount of copper packing is .33kg per 100mm for a 4" i did the math and its 1.65kg of mesh.
That's a bit of a bugger... Do i buy 1.5kg and hope its enough, or should i get 2kg and have left over LOL.
It would be great if you had an option on the store to buy both together.
Cheers
