Product Description
The Simpson APB66 Ornamental 6x6 Post Base is a decorative, black powder-coated post base engineered by Simpson to anchor a 6x6 post or column securely to concrete in outdoor structural applications. Built from 12-gauge steel with ZMAX galvanization beneath a black powder-coat finish, this post base is purpose-built for pergolas, patio covers, and other top-supported outdoor structures where long-term corrosion resistance and structural integrity are both required. The ornamental profile adds a finished, intentional look to exposed post connections without sacrificing the load-transfer performance demanded by modern building codes.
Key Features
- ZMAX galvanization with black powder-coat finish - provides a dual layer of corrosion protection, making this base well-suited for exterior environments and treated-wood applications where moisture and chemical exposure are ongoing concerns
- 1 in. standoff from concrete surface - lifts the post end away from direct contact with concrete, reducing moisture accumulation at the base of the post and helping prevent post-end rot over time
- Slotted design - allows for positional adjustability during installation so the post can be aligned precisely without being locked into a single fixed anchor point
- Designed to meet stringent building codes for seismic or high-wind events - provides the structural performance needed in demanding regions, giving builders and homeowners confidence in long-term safety and code compliance
- Offset fastener holes - holes are slightly offset to help prevent fastener interference during installation, reducing the risk of splitting or misalignment when driving fasteners
- Compatible with Outdoor Accents decorative side plates - the base accepts separately available side plates (see APBDSP) for a more finished ornamental appearance on visible post connections
- Made from 12-gauge steel - heavy-gauge construction delivers the rigidity and strength required for load-bearing post base applications in permanent outdoor structures
Why This Product
- Form and function in a single component - the ornamental profile and black powder-coat finish mean this post base looks intentional and refined at exposed connections in pergolas and patio covers, eliminating the need to hide utilitarian hardware behind trim or cladding
- Built-in rot prevention extends post life - the 1 in. standoff is a design detail that pays long-term dividends by keeping post ends dry, helping protect the investment in the structural lumber itself
- Dual-layer corrosion resistance stands up to outdoor conditions - ZMAX galvanization combined with a black powder coat delivers extra protection against the weathering, moisture, and chemical exposure that are unavoidable in exterior and treated-wood applications
- Code-compliant performance for high-demand installations - engineered to meet stringent building code requirements for seismic and high-wind regions, this post base is appropriate for projects where structural hardware must satisfy formal inspection and permitting requirements

Frequently Asked Questions
- What fasteners are required to install the APB66 post base?
- Install with (4) STN22 Outdoor Accents hex-head washers and (4) SDWS22312DBB Outdoor Accents structural wood screws, along with a 5/8 in. concrete anchor. Fasteners are sold separately.
- Why does the APB66 feature a 1 in. standoff?
- The 1 in. standoff lifts the post end away from the concrete surface to help prevent moisture accumulation at the post end, which in turn helps avoid post-end rot over time.
- Is the APB66 suitable for high-wind or seismic regions?
- Yes. The APB66 is designed to meet stringent building codes for seismic or high-wind events, making it appropriate for use in regions with demanding structural requirements.
- Can decorative side plates be added to the APB66 post base?
- Yes. Outdoor Accents side plates are available separately. See for the compatible decorative side plate option.
