Hi Ken,
Yes they are square, I need 3 sections about 3' long each... you may not have that much... I will pay you when I see you in NO for whatever you do have or if you have a source where I can order it? Google wasn't much help since I wasn't sure exactly what it's called.
I will tell Larry about the sausage he will be happy !!
Thanks Ken- we'll see you in NO soon.
Diane
