Does anyone know where you could buy 2.5 " sq. PVC. it is out there somewhere I just dont know where.I tried hom depot ,Menards and,lowesThank you.

there are a few places that will sell it. check the mom and pop hardware stores. ACE, true value maybe. ask for catalogs of plastic raingutter.

I have two 30+inch pieces that I would sell you for the price of postage and a large diet coke. I had a long piece and cut 30inches's off for a spad. I made the same offer on here to another flyer and he never contacted me again. If you can't get it locally then contact me and you can have the two pieces that I have.

do it best and ace hardware carries it around here

Ace and True Value Hardware stores have been my suppliers in a couple of different towns, in both Texas and Illinois. Rich

It's getting hard to come by. Do it Best Centers advertise that they have it and will ship to your local store. I got mine at Simms Do it Best Center in Weatherford, TX. BTW, most combat fliers are no longer using it because it is heavy and tends to shatter on impact, But it's good for SPAD's. Good Luck.
