Alro stocks DOM tubing... thats were i buy everything now... When you do and if you do buy dom, make sure they call and check for lengths, I bought 6 pieces and the guy said ya there 21', got there to pick them up "prepaid" and they were 18' at 3.00 per foot, 18' of tubing is a lot to be off...Another time i had a lady answer, she said this is the price regardless of the length...Told her she was fxxking nuts...
