I have 2 12 inch roof jacks and 1 14 inch roof jack that I am looking to get rid of. They are all for a 7/12 pitch roof and in good shape. Stupid me changed the pitch of the roof and now I need new ones. asking $50 a piece and I can throw a stack cover in with the 14 inch roof jack if that is wanted. Perfect set for someone that has 2 hood stacks and 1 arch stack. I can provide pictures if someone is interested. Call or text (802) 88one 602six if you are interested
