Maximum arc for 12mm Easton poles

12 mm = .47244″ or close to 1/2″.  The closest dia. of Easton pole that Quest sells is .490″.  While I think that would flex to the arc you describe, it might be wise to contact Easton, give them the arc length and height, and inquire whether the .490″ dia. alloy pole is suited to bend to that arc for use in a tent.

Yes they are 0.490″ I used 12mm as an approximation. Some NOS in precurved are available locally, I picked up a dozen of them just in case; as the cost was right.

One of the reasons for asking here is that Easton have not replied to my emails asking for help.

In the past, they have responded to me, eventually. Also, have been able to reach people in sales who were helpful. They only sell larger quantities wholesale, so do not have a strong orientation to end users. One trouble with email is that if people don’t follow your message, they may just ignore it and not respond. This, as opposed to asking a question or two on the phone to clarify, and then responding. It is one of the banes of modern life.

I experimented.

I took 3 of my pre-curved 26 inch sections and put 2 straight 26inch sections on each end and  curved them to ~1800mm wide and ~1800mm tall and the poles curved with no real muscle effort so I’ll try again in a while using 3 sections on each side, a total pole length of approximately 19 feet//5.9 metres.

I probably will not go ahead with the project tho, my winter skiing and camping is starting to create far too much marital friction
