The Simpson APB1010 Outdoor Accents Mission Collection Post Base is a decorative structural connector engineered to anchor a 10x10 post or column securely to concrete for outdoor applications including pergolas, patio covers, and other top-supported structures. Built by Simpson with a ZMAX galvanized base and a black powder-coat finish on the straps, this post base balances code-compliant structural integrity with clean, refined aesthetics suited to finished outdoor builds.

Key Features

• Designed to meet stringent building codes for seismic or high-wind events - gives you confidence that the connection point holds up under the conditions that matter most, without requiring additional engineering workarounds.
• Slotted for adjustability - makes field alignment easier when anchor bolt placement is not perfectly precise, saving time during installation.
• 1-in. standoff from the concrete surface - elevates the post end away from standing moisture, directly reducing the risk of rot at the base of the post over time.
• Fastener holes are slightly offset - helps prevent fastener interference during installation so screws seat properly without splitting or competing for the same wood fiber.
• ZMAX galvanization on the base - provides extra corrosion resistance built for exterior environments and treated-wood applications where standard coatings fall short.
• Black powder-coat finish on the straps - adds a polished decorative look that complements finished pergola and patio cover designs without sacrificing corrosion protection.
• Base 14 ga., straps 12 ga. steel construction - delivers the thickness and rigidity appropriate for a heavy 10x10 structural post in load-bearing outdoor applications.
• Compatible with Outdoor Accents side plates (APBDSP) - allows you to extend the decorative treatment for a fully finished, cohesive appearance on all visible sides of the post base.
• Install with STN22 hex-head washers and SDWS22312DBB structural wood screws - the recommended Outdoor Accents fastener system keeps the hardware finish consistent with the black powder-coat aesthetic of the base itself.

Why This Product

• Structural performance meets finished aesthetics - the combination of ZMAX galvanization beneath a black powder-coat finish means this post base is built to resist corrosion in demanding exterior conditions while still looking intentional and refined on a pergola or patio structure.
• Purpose-built rot protection - the integrated 1-in. standoff is a practical design detail that actively works to protect your post investment by keeping wood off wet concrete, a common and costly failure point in outdoor post installations.
• Engineered for large-scale outdoor projects - sized specifically for a nominal 10x10 post, this base is suited to the heavier structural demands of larger pergolas and patio covers where undersized hardware is not an option.
• Code-ready for high-wind and seismic zones - meeting stringent building code requirements for seismic and high-wind events means this connector can be specified with confidence in regions where those load conditions are part of the permitting conversation.

Frequently Asked Questions

What size post is the APB1010 designed for?

The APB1010 is designed for a nominal 10x10 post or column, making it ideal for larger structural applications such as pergolas and patio covers.

Why does the APB1010 include a 1-inch standoff?

The 1-in. standoff elevates the base of the post away from the concrete surface, helping to prevent moisture accumulation at the post end and reducing the risk of rot over time.

What fasteners are required to install the APB1010?

Install with (8) STN22 Outdoor Accents hex-head washers and (8) SDWS22312DBB Outdoor Accents structural wood screws, along with (2) 5/8-in. concrete anchors to secure the base to concrete.

Is the APB1010 rated for use in high-wind or seismic zones?

Yes. The APB1010 is designed to meet stringent building codes for seismic or high-wind events, providing reliable structural performance in demanding conditions.
