The Simpson Avant Collection APVB88R post base is engineered to anchor an 8x8 rough post or column securely to concrete for outdoor structures including pergolas, patio covers, and other top-supported applications. Part of the Outdoor Accents Avant Collection from Simpson, this ornamental post base pairs a clean, simple aesthetic with ZMAX galvanization and a black powder-coat finish, delivering layered corrosion resistance suited for exterior environments and treated-wood construction. A built-in 1 in. standoff elevates the post end above the concrete surface to help guard against moisture-related rot, while slotted holes allow for on-site adjustability during installation.

Key Features

• Meets stringent building codes for seismic or high-wind events - gives builders and homeowners confidence that the connection is engineered for demanding structural conditions, not just everyday loads.
• Slotted hole pattern - allows field adjustability during installation so the post can be precisely positioned without starting over.
• 1 in. standoff from the concrete surface - keeps the post end elevated above pooling moisture, directly reducing the risk of rot at the base of the column over time.
• Offset fastener holes - reduces the chance of fasteners interfering with one another during installation, making the process cleaner and more reliable (fasteners sold separately).
• Base formed from 14-gauge steel; straps formed from 12-gauge steel - heavier-gauge straps provide added rigidity and strength at the connection points that matter most.
• ZMAX galvanization plus black powder-coat finish on both base and straps - dual-layer protection resists corrosion in exterior and treated-wood environments while the black finish keeps the hardware looking intentional rather than purely utilitarian.
• Compatible with Outdoor Accents side plates (see APVBDSP) - lets builders complete the decorative look of the post base for finished outdoor living spaces where visible hardware is part of the design.
• Install with STN22 hex-head washers and SDWS22312DBB structural wood screws - dedicated Outdoor Accents fasteners are available as a matched set, keeping the hardware finish consistent across the entire connection.

Why This Product

• Function and finish in one product - the ZMAX galvanized base with black powder-coat on both the base and decorative straps means this post base handles corrosion resistance and visual appeal at the same time, eliminating the need to hide or paint over exposed hardware.
• Built-in rot prevention - the 1 in. standoff is a structural detail that actively extends the service life of the post by breaking the direct contact between wood and concrete where moisture tends to collect.
• Code-ready for challenging climates - designed to meet seismic and high-wind building code requirements, this post base is a practical choice for pergola and patio cover projects in regions where structural connections face regulatory scrutiny.
• Designed for real outdoor use - the combination of heavy-gauge steel construction, ZMAX galvanization, and a powder-coat finish makes this base appropriate for long-term exterior and treated-wood applications where lesser hardware would corrode or fail prematurely.

Frequently Asked Questions

What post size is the APVB88R designed to fit?

The APVB88R is designed for a nominal 8x8 rough post size, making it suitable for substantial structural columns used in pergolas, patio covers, and similar top-supported outdoor structures.

Why does this post base include a 1 in. standoff?

The 1 in. standoff elevates the post end above the concrete surface, helping to prevent moisture accumulation at the base of the post that could otherwise lead to rot over time.

What fasteners are required to install the APVB88R?

Installation requires (8) STN22 Outdoor Accents hex-head washers and (8) SDWS22312DBB Outdoor Accents structural wood screws. These fasteners are not included with the post base and must be purchased separately.

Is the APVB88R suitable for use in high-wind or seismic zones?

Yes. The APVB88R is designed to meet stringent building codes for seismic or high-wind events, making it appropriate for installations in regions subject to these conditions.

Note: The structural screws, hex head washers, and concrete anchors are not included.
