Post kits are available for all of our signs and made from pressure treated 4 "x 4" Hemlock. Posts are hand picked with routed edges for safer handling. Each post is covered in a UV protective paint, cut to size per the instructions and have marked pre drilled holes for easy sign mounting and installation. Each post comes with an attached pre fabricated powder coated aluminum top cap to prevent moisture from entering the post. This top cap also gives a professional finished look to the final installed sign.
