I was shipped a single tube, 18" dia. x 56" l, by mistake. I wanted a quote, but was charged. Anyway, I really don't need it. Whitecap industries Charged $30 total, and if anyone happens to need it, I'd be glad to take $25 for it, you pick up. Delivery possible. Call me for details at 952 988 1210, 7AM to 3PM. Located in Richfield, just South of Minneapolis. Thanks!
