APB Adjustable Post Base

APB

Outdoor Accents 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 feature decorative accents and provide ZMAX® galvanization over a black powder coat for extra corrosion resistance.

APB models include a 1" standoff from the concrete to help avoid post-end rot caused by moisture.

Key Features

  • Designed to meet stringent building codes for seismic or high-wind events
  • Install with Outdoor Accents structural wood screws and hex-head washers (sold separately) for a decorative look
  • Slotted for adjustability

Material

  • See table

Finish

  • ZMAX® with textured powder-coated, flat black paint; APB88 and APB1010 standoff base — ZMAX only

Installation

  • Use all specified fasteners; see General Notes
  • Use of the Outdoor Accents connectors requires use of the hex-head washer (STN22) and structural wood screw (SDWSDBB)

  1. Uplift loads have been increased for wind or earthquake or seismic with no further increase allowed; reduce where others govern.
  2. Downloads may not be increased for short-term loading.
  3. Specifier to design concrete for uplift capacity.
  4. Downloads shall be reduced where limited by capacity of the post.
  5. All post fasteners are a Simpson Strong-Tie® SDWS22312DBB inserted through an STN22 washer.
  6. Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations (such as fences or unbraced carports).
