Product Description
The Simpson 6 x 5 Adjustable Post Base ZMAX is a heavy-duty structural connector engineered by Simpson to anchor wooden posts securely to existing concrete in high-capacity applications. Built with a ZMAX corrosion-resistant coating and a built-in 1 in. standoff, this adjustable post base is designed to deliver reliable uplift performance while helping protect post ends from moisture-related deterioration - making it a dependable choice for decks, pergolas, carports, and other demanding structural installations.
Key Features
- Built-in 1 in. standoff - elevates the post end above the concrete surface, reducing moisture contact and helping guard against rot for a longer-lasting installation
- Slotted anchor hole in the base plate - allows lateral adjustability when positioning over an anchor bolt set in concrete, making alignment easier during installation
- ZMAX heavy-duty galvanized coating - provides enhanced corrosion resistance suited for use with treated lumber and in environments where moisture or chemical exposure is a concern
- Compatible with multiple fastener types - accepts nails, Strong-Drive SD Connector screws, or bolts, giving installers flexibility to match fastening method to project requirements
- 12-gauge base and 10-gauge strap construction - delivers the structural strength needed for high-capacity post anchoring applications where performance under load matters
- Designed for attachment to existing concrete - suited for retrofit and new construction scenarios where a post must be anchored to a poured concrete foundation or slab
Why This Product
- Built-in moisture protection - the 1 in. standoff keeps the post end clear of the concrete surface, directly reducing the risk of rot and helping extend the service life of the post without requiring additional accessories
- Adjustability that saves time on the job - the slotted anchor hole makes it straightforward to fine-tune positioning over an existing anchor bolt, reducing frustration and rework during post placement
- ZMAX coating for demanding environments - the enhanced galvanized finish goes beyond standard corrosion protection, making this post base a practical choice for treated lumber applications and outdoor structural projects exposed to the elements
- American-made quality from a trusted brand - produced in the United States by Simpson, a name widely recognized in structural connectors, this post base is built to perform in real-world construction conditions

Frequently Asked Questions
- What type of standoff does the ABU65Z include, and why does it matter?
- The ABU65Z features a built-in 1" standoff that elevates the base of the wooden post above the concrete surface. This separation helps prevent moisture from accumulating at the post end, significantly reducing the risk of rot and extending the service life of the post.
- What fasteners are required to install the ABU65Z?
- Installation requires (1) 5/8" anchor to secure the base to the concrete and (12) 0.162" x 3-1/2" nails to attach the post. The connector can also be fastened with Strong-Drive SD Connector screws or bolts for added versatility.
- What does the ZMAX coating provide?
- The ZMAX coating is a heavy-duty galvanized finish that offers enhanced corrosion resistance compared to standard galvanized connectors, making the ABU65Z well-suited for use in treated lumber and other demanding environments where moisture or chemical exposure may be a concern.
- Is the ABU65Z adjustable, and how does that work?
- Yes. The ABU65Z includes a slotted anchor hole in the base plate, which allows for lateral adjustability when positioning the post base over an anchor bolt set in concrete. This makes it easier to align the post base accurately even if the anchor placement is not perfectly precise.
