APVB Adjustable Post Base


On This Page

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.

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.

Key Features

  • Designed to meet stringent building codes for seismic or high-wind events
  • Slotted for adjustability
  • Features 1" standoff to help prevent rot at post end
  • Outdoor Accents side plates available (see APVBDSP)
  • Fastener holes are slightly offset to help prevent fastener interference

  • ZMAX galvanization with a black powder coat offers extra corrosion resistance for exterior and treated-wood applications
