Outdoor Accents adjustable post bases secure the post or column to concrete and are perfect for outdoor projects, such as pergolas, patio covers, and other top-supported structures. These post bases are part of our outdoor Accents Avant collection and feature a clean, timeless design that complements nearly every architectural style. Zmax galvanized steel with a black powder-coat finish provides corrosion resistance. This screw and washer combination provides a decorative bolt-like connection, but with the installation ease of a screw. APVB models include a 1 in. standoff from the concrete to help avoid post-end rot from moisture.
