Most dealers sell it in 500' rolls, Leader dealers have it in 400' and 800' rolls. Heritage Maple in Canastota, NY has it in 500' rolls by D&G. They are just 6 miles from me, but he does ship. Amish, no website but he advertises in The Maple News. Before he started carrying it, I used to order it From Homestead Maple in Chazy, NY. He has a website, google it. As I said, many other dealers will have it in 500' rolls.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
