Outdoor Accents® adjustable post-bases secure the post or column to concrete and are ideal for outdoor projects such as pergolas, patio covers and other top-supported structures. These post-bases are part of our Outdoor Accents® Mission Collection® and feature decorative edges with a southwestern flair that bring design elegance to your outdoor living areas. ZMAX® galvanized steel with a black powder-coat finish provides corrosion resistance. The APB post-bases install with the Outdoor Accents® structural wood screw and patented hex head washer (sold separately) the only approved fastener solution for Outdoor Accents® connectors. This screw and washer combination provides a decorative bolt-like connection, with the installation ease of a screw. APB models include a 1 in stand-off from the concrete to help avoid post-end rot caused by moisture.
