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 for gazebos.

The APVB 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, but with the installation ease of a screw. APVB models include a 1″ standoff from the concrete to help avoid post-end rot from moisture.
