Bought the pressure treated last year, was so wet I couldn't lift it! Grapes don't have leaves on them most of the year. Was originally gona go with all 143s 'cause they remind me of big grapes, but I like 'm to much! Update2018: Grapes kept growing, Snow piled up, and it hinged down still attached to garage. In retrospect, thinking that using those galvanized bars I'd gotten off old poles as braces was just a bad idea in this application. Those braces on poles are on both sides of pole, not just one for a reason. When one side is under compression, the other is under tension.
