The Simpson Outdoor Accents Sage System Post Base for 6x6 - Black Powder-Coated, 2-Pack with Screws gives homeowners and DIYers a tested, code-listed solution for anchoring 6x6 posts securely to existing concrete when building pergolas and other outdoor structures. Constructed from heavy-duty 12-gauge ZMAX-galvanized steel with a decorative black powder-coat finish, this post base pairs structural reliability with clean, consistent aesthetics that complement the full Outdoor Accents Sage System. Outside flanges offer the flexibility of attaching to the concrete before or after the structure is complete, and every fastener needed for a full installation is included in the kit.

Key Features

• Attaches securely to existing concrete with included Titen Turbo screw anchors - no need to source additional anchors; predrilling is required, but all concrete fasteners are in the box so installation stays on track from the start.
• 12-gauge ZMAX-galvanized steel with corrosion-resistant construction - delivers superior resistance to outdoor weather conditions, helping the hardware hold up season after season in exposed environments.
• Built-in standoff elevates the post base above the concrete surface - reduces direct contact between the post end and moisture, helping prevent wood rot and extending the working life of your pergola posts.
• Outside flanges allow flexible installation sequencing - attach to the concrete before or after the pergola is finished, giving you options that suit your build process and timeline.
• Decorative black powder-coat finish - matches other Outdoor Accents Sage System connectors for a cohesive, polished look across the entire structure.
• Color-matched Outdoor Accents connector screws included - fastener heads blend with the black finish so hardware stays visually consistent and does not interrupt the clean lines of the finished pergola.
• Quantity: 2 post base connectors per package - covers two post locations in a single purchase, reducing the number of orders needed for a multi-post pergola project.

Why This Product

• A complete, code-listed anchoring kit ready to install - the package includes both post bases along with all required connector screws and Titen Turbo concrete anchors, so you are not hunting for compatible hardware separately. The tested and code-listed design also provides confidence that the connection meets recognized structural standards.
• Dual-layer corrosion protection built for outdoor exposure - ZMAX galvanization combined with a black powder-coat finish means the steel is protected from the inside out, making these post bases well suited to decks, patios, and garden pergolas exposed to rain and humidity.
• Moisture management built into the base design - the integrated standoff keeps the post end off the concrete surface, directly addressing one of the most common causes of premature wood failure in outdoor post installations.
• Aesthetic continuity across the full Sage System - the consistent black finish and color-matched screws allow these post bases to integrate seamlessly with other Outdoor Accents Sage connectors, making it easier to achieve a unified, intentional look without extra finishing work.

Frequently Asked Questions

What post size is the SAGE-B66-KT2 designed for?

The SAGE-B66-KT2 post base is designed for a nominal 6x6 member size, making it suitable for standard 6x6 lumber posts used in pergola and outdoor structure construction.

Does this kit include all the fasteners needed for installation?

Yes. Each kit includes (28) SD10112DBB Outdoor Accents connector screws and (16) TNTBL25134H Titen Turbo concrete and masonry screws - enough hardware to fully install both post bases included in the package. Note that predrilling into the concrete is required before installing the Titen Turbo screw anchors.

How does the built-in standoff benefit my pergola posts?

The built-in standoff elevates the base of the post slightly above the concrete surface, which helps prevent post-end wood rot caused by moisture accumulation - a key durability advantage for outdoor applications exposed to rain and humidity.

Can the post base be attached to the concrete after the pergola structure is already built?

Yes. The outside flange design of the SAGE-B66-KT2 offers flexible installation, allowing the base to be attached to the concrete either before or after the pergola is assembled and finished.
