The Simpson APB1010R Ornamental Rough Cut 10x10 Post Base is part of the Simpson Outdoor Accents Mission Collection, purpose-built to anchor a rough cut 10x10 post or column securely to concrete for outdoor structures including pergolas, patio covers, and other top-supported builds. A dual-layer finish combining ZMAX galvanization with a black powder coat delivers enhanced corrosion resistance for exterior and treated-wood environments, while the ornamental strap design ensures the hardware contributes to the finished look of the structure rather than detracting from it.

Key Features

• Designed to meet 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 light-duty use.
• Slotted for adjustability - allows for minor positioning corrections during installation, reducing the risk of a misaligned post location locking in an irreversible mistake.
• 1 in. standoff from the concrete surface - elevates the post end above moisture that can collect at the base, helping prevent post-end rot and extending the service life of the entire structure.
• Fastener holes are slightly offset to help prevent fastener interference - fasteners go in cleanly without splitting the post or conflicting with one another (fasteners sold separately).
• Base 14 ga. steel with 12 ga. straps - heavier strap gauge at the critical load-transfer zone means the hardware holds its shape and strength under the loads a large rough cut post puts on it.
• ZMAX galvanization with black powder coat on the straps - the layered finish resists corrosion in outdoor and treated-wood environments while keeping the visible hardware looking intentional and finished.
• Compatible with Outdoor Accents side plates (see APBDSP) - lets builders extend the decorative look around all four sides of the post base for a fully finished architectural appearance.
• Sized specifically for a true rough cut 10x10 post with an actual 10 in. x 10 in. dimension - eliminates fit problems that arise when the wrong base is ordered for a nominal-dimensioned post.

Why This Product

• Structural performance and decorative finish in a single fitting - the ZMAX galvanization handles long-term corrosion resistance in treated-wood and outdoor settings while the black powder coat on the straps makes the base a visible design element, removing the need to choose between a code-compliant connection and good-looking hardware.
• Built-in moisture protection at the most vulnerable point - the 1 in. standoff is a passive, maintenance-free detail that keeps the post end off the concrete, directly addressing one of the most common causes of premature post failure in outdoor structures like pergolas and patio covers.
• Code-ready for demanding conditions - designed to meet stringent building codes for seismic or high-wind events, this post base supports permit approval and professional installation in regions where load requirements are strictly enforced.
• Precision fit for rough cut timber - sized for an actual 10 in. x 10 in. post rather than nominal lumber, so the base fits the timber correctly from the start, producing a stable, gap-free connection without shimming or improvised adjustments.

Frequently Asked Questions

What size post does the APB1010R fit?

The APB1010R is designed specifically for a rough cut 10x10 post - meaning the post must have an actual measured dimension of 10 in. x 10 in. It is not compatible with nominal 10x10 lumber, which typically measures 9-1/2 in. x 9-1/2 in. For nominal-sized posts, see the APB1010.

How does the 1 in. standoff help protect the post?

The built-in 1 in. standoff elevates the post end above the concrete surface, reducing direct contact with moisture that can accumulate at the base. This helps prevent post-end rot and extends the service life of the structure.

Is the APB1010R suitable for high-wind or seismic regions?

Yes. The APB1010R is designed to meet stringent building codes for seismic or high-wind events, making it appropriate for use in areas with elevated structural load requirements.

What finish does the APB1010R have, and is it suitable for exterior use?

The APB1010R features ZMAX galvanization with a black powder-coat finish. ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications, and the black powder coat on the straps adds a decorative look suited for visible outdoor installations such as pergolas and patio covers.

Note: This connector is designed for Rough Cut lumber, NOT nominal lumber (most common). This will only fit a post that measures an actual 10 in. x 10 in. If you have a nominal post measuring 9-1/2 in. x 9-1/2 in., you will need the Ornamental Post Base.
