This is a \u003cstrong\u003epost base\u003c\/strong\u003e designed for \u003cstrong\u003ewood-to-concrete post anchoring\u003c\/strong\u003e. Model Number: \u003cstrong\u003eAPB66\u003c\/strong\u003e. If you are building a pergola, patio cover, deck post connection, or another top-supported structure and want a cleaner finished look than a standard utility base, this hardware is built for that job.\u003c\/p\u003e\n      \u003cp\u003eWhat makes this base matter is how it solves a few real install problems at once. The slotted design gives you adjustment room when setting the post, which helps when field conditions are not perfect. The base also includes a \u003cstrong\u003e1 inch standoff\u003c\/strong\u003e that lifts the post off the concrete. That gap is important because it helps limit direct moisture contact at the post end, which can reduce the chance of rot over time in exterior applications.\u003c\/p\u003e\n      \u003cp\u003eFor strength and code-driven applications, Simpson rates this series for projects that need to meet stringent building code requirements for \u003cstrong\u003eseismic or high-wind events\u003c\/strong\u003e. That does not mean every job is the same, but it does tell you this is not just decorative trim hardware. It is structural connector hardware that also happens to look better than most standard bases. The fastener holes are slightly offset as well, which helps reduce fastener interference during installation.\u003c\/p\u003e\n      \u003cp\u003eThe APB66 is part of the Outdoor Accents Mission Collection, so it is aimed at builders who want a more finished exposed-hardware look on the job. The black powder-coated appearance gives you the visual style people want on pergolas and outdoor living structures, while the \u003cstrong\u003eZMAX coating with black powder coat\u003c\/strong\u003e adds corrosion resistance for exterior and treated-wood use. In plain terms, it is made to be seen, not hidden.\u003c\/p\u003e\n      \u003cp\u003eSize-wise, this APB66 version is built for a \u003cstrong\u003enominal 6x6 post\u003c\/strong\u003e. Simpson lists it with a \u003cstrong\u003e12-gauge steel body\u003c\/strong\u003e, a width of \u003cstrong\u003e5-1\/2 inches\u003c\/strong\u003e, a length of \u003cstrong\u003e5 inches\u003c\/strong\u003e, and a height of \u003cstrong\u003e7-1\/2 inches\u003c\/strong\u003e. Those numbers matter because they tell you this base is sized specifically around nominal 6x6 material, not rough lumber. If you are using rough 6x6 stock, Simpson offers a separate APB66R version instead.\u003c\/p\u003e\n      \u003cp\u003eInstallation hardware matters here. The Outdoor Accents connector system is intended to be used with the \u003cstrong\u003eSTN22 hex-head washer\u003c\/strong\u003e and \u003cstrong\u003eSDWS22312DBB structural wood screw\u003c\/strong\u003e, which are sold separately. That combination gives the connection its intended structural and visual result. Outdoor Accents side plates are also available under \u003cstrong\u003eAPBDSP\u003c\/strong\u003e if your build calls for matching hardware details across the structure.\u003c\/p\u003e\n      \u003cp\u003eOne practical note worth knowing before you buy: this type of post base is intended for \u003cstrong\u003etop-supported structures\u003c\/strong\u003e. Simpson specifically notes these bases are not recommended for installations that lack top support, such as fences or unbraced carports, because they do not provide enough resistance to prevent members from rotating at the base. That is the kind of detail that saves you from using the right hardware in the wrong application.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is a good fit for deck builders, pergola installers, remodelers, and serious DIYers who want a cleaner exposed connection at the bottom of a 6x6 post without giving up structural intent. If you are building an outdoor structure where appearance matters and you still need a real post-to-footing connector, the APB66 is the right kind of hardware for the job.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eKeeps the Post Up Off the Concrete\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/ssttoolbox.widen.net\/content\/q7dyard5j8\/jpeg\/C_ABP44_InstPho_Pho_Instld_OutdoorAccentsMission-AdjustablePostBase-Concrete-Grass_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie APB66 adjustable post base style installed on an outdoor wood post anchored to a concrete slab beside grass\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThe biggest long-term advantage here is simple: the post is not sitting flat on wet concrete.
