Full 6″ x 12″ Appearance grade Alaskan yellow cedar. Outperforms other lumber types including pressure treated for outdoor use, even buried in the ground. Appearance grade means small tight knots and a fair amount of clear, knot free wood. Full rough dimension means we can have this made into a variety of sizes, patterns and profiles. Use as is for any outdoor use including decks, arbors, pergolas even in the dirt. Always check for available lengths.
