Product Description
The Simpson Avant Rough 6x6 Ornamental Post Base is part of the Outdoor Accents Avant Collection, engineered to anchor a 6x6 rough post or column to concrete for outdoor structures including pergolas, patio covers, and other top-supported applications. Built from 12-gauge steel with ZMAX galvanization and a black powder-coat finish, this post base delivers durable corrosion resistance suited for exterior and treated-wood use, while its clean, simple profile brings a polished look to exposed structural connections. The integrated 1 in. standoff and offset fastener holes reflect the kind of practical engineering details that make a difference over the life of an outdoor structure.
Key Features
- Designed to meet stringent building codes for seismic or high-wind events - gives you confidence that the connection point meets code requirements in demanding structural and regional conditions.
- Slotted for adjustability - allows fine-tuning of post position during installation so alignment is easier to achieve on real-world job sites.
- 1 in. standoff from the concrete surface - raises the post end off the slab to promote airflow and reduce prolonged moisture contact, helping prevent rot at the base of the post over time.
- Fastener holes are slightly offset - reduces the risk of fasteners interfering with one another during installation, making the fastening process cleaner and more reliable (fasteners sold separately).
- 12-gauge steel construction - provides the structural strength appropriate for larger 6x6 post applications such as pergola and patio cover framing.
- ZMAX galvanization with a black powder-coat finish - layers two forms of corrosion protection for long-term performance in exterior environments and alongside treated lumber.
- Outdoor Accents side plates available separately (see APVBDSP) - lets you extend the decorative detailing of the Avant Collection to the sides of the base for a more finished, cohesive appearance.
Why This Product
- Structural performance with a refined look - the Avant Collection design keeps the hardware visually clean and intentional, so the post base becomes part of the aesthetic of a pergola or patio cover rather than something to hide.
- Built-in moisture management - the 1 in. standoff is a detail that directly extends the service life of your post by keeping end grain off the concrete, addressing one of the most common causes of post failure in outdoor installations.
- Dual-layer corrosion protection - ZMAX galvanization combined with a black powder coat means this base is engineered specifically to hold up in the exterior and treated-wood conditions where post bases are most commonly used.
- Code-compliance ready for challenging locations - meeting stringent seismic and high-wind building code requirements means this base is appropriate for a wider range of project locations and permits without requiring a specialty solution.

Frequently Asked Questions
- What post size is the APVB66R designed for?
- The APVB66R is designed for a nominal 6x6 rough post or column, making it well-suited for larger pergola and patio cover structures that require a sturdy anchor point at the base.
- Why does this post base include a 1 in. standoff?
- The 1 in. standoff raises the post end off the concrete surface to allow airflow and reduce prolonged moisture contact, which helps prevent rot at the bottom of the post over time.
- Is the APVB66R rated for use in high-wind or seismic regions?
- Yes. The APVB66R is designed to meet stringent building codes for both seismic and high-wind events, making it appropriate for use in demanding structural applications where code compliance is required.
- What fasteners are required to install the APVB66R?
- Installation requires (4) STN22 Outdoor Accents hex-head washers and (4) SDWS22312DBB Outdoor Accents structural wood screws. A concrete anchor is also needed to secure the base to the concrete. These fasteners are not included with the post base and must be obtained separately.
