Product Description
The Simpson Outdoor Accents Avant Collection ZMAX Black Powder-Coated Post Base for 4x4 is a structurally engineered connector designed to anchor a post or column securely to concrete, making it a reliable choice for outdoor builds such as pergolas, patio covers, and other top-supported structures. Its clean, simple design integrates a ZMAX galvanized base with a black powder-coat finish, delivering the corrosion resistance needed for exterior environments and treated-lumber applications while maintaining a refined ornamental appearance that complements finished outdoor spaces.
Key Features
- Meets stringent building codes for seismic or high-wind events - gives builders and homeowners confidence that the connection point is engineered for real structural demands, not just everyday loads.
- Slotted for adjustability - allows fine-tuned post positioning during installation, saving time and reducing the risk of misalignment on the finished structure.
- 1 in. standoff from the concrete surface - elevates the post end above potential moisture accumulation, directly reducing the risk of post-end rot over the life of the structure.
- Slightly offset fastener holes - prevents fastener interference during installation, resulting in a cleaner, more secure connection without crowding or splitting the wood.
- ZMAX galvanization with black powder-coat finish - provides extra corrosion resistance suited for exterior and treated-wood applications, keeping the base performing and looking sharp in harsh outdoor conditions.
- Base 16 ga. steel with 12 ga. straps - the heavier-gauge straps where structural stress concentrates means the base holds its integrity under load without unnecessary bulk in the base plate.
- Compatible with Outdoor Accents side plates (APVBDSP) - allows buyers to extend the ornamental aesthetic of the Avant Collection across the full post base assembly for a cohesive finished look.
- Installs with STN22 hex-head washers and SDWS22312DBB structural wood screws - a defined fastener system means no guesswork about hardware compatibility, simplifying procurement and inspection.
Why This Product
- Form and function built into one connector - the Avant Collection design delivers the clean ornamental look expected in a finished pergola or patio cover without sacrificing the structural performance required by seismic and high-wind building codes.
- Extra-durable finish for challenging outdoor environments - the combination of ZMAX galvanization and black powder-coat finish offers a two-layer approach to corrosion resistance, making this post base a sound long-term investment for exterior and pressure-treated lumber applications.
- Built-in rot prevention from day one - the 1 in. standoff is not an add-on or an afterthought; it is engineered directly into the base to keep the post end clear of standing moisture, protecting the structural integrity of the post over years of outdoor exposure.
- A defined, code-aware installation system - with a specified fastener pairing and offset hole placement that prevents interference, this post base is designed to go in correctly the first time, supporting accurate, inspection-ready results on pergolas, patio covers, and similar column-to-concrete connections.

Frequently Asked Questions
- What is the purpose of the 1 in. standoff on the APVB44 post base?
- The 1 in. standoff elevates the post end above the concrete surface, helping to prevent moisture accumulation at the base of the post and reducing the risk of post-end rot over time.
- Is the APVB44 suitable for use with pressure-treated lumber?
- Yes. The ZMAX galvanization combined with a black powder-coat finish provides extra corrosion resistance, making this post base well-suited for exterior and treated-wood applications.
- What fasteners are required to install the APVB44 post base?
- Installation requires (4) STN22 Outdoor Accents hex-head washers and (4) SDWS22312DBB Outdoor Accents structural wood screws. Please note that structural screws, hex head washers, and concrete anchors are not included with the post base.
- Is the APVB44 designed to meet building code requirements for high-wind or seismic zones?
- Yes. The APVB44 is designed to meet stringent building codes for seismic or high-wind events, making it appropriate for use in regions with elevated structural performance requirements.
