The Simpson Outdoor Accents Mission Collection Decorative Post Base Cover for 6x6 Post brings a polished, finished look to exposed post base hardware on decks, pergolas, and other outdoor living structures. Part of Simpson's Outdoor Accents line - a family of connectors and fasteners designed to unite beauty and structural performance - this four-piece composite wrap features the arched profile of the Mission Collection, concealing post base hardware beneath a clean, cohesive decorative cover that requires no drilling into the post itself.

Key Features

• Compatible with multiple post base models (screw and nail application only) - wraps around the MPBZ moment post base as well as the CBSQ, ABUZ, ABWZ, and ABAZ post bases, giving builders flexibility across a range of common post base installations without purchasing a separate decorative solution for each.
• Four-piece cover screws together outside the post base with screws included - no additional hardware to source and no specialized tools required, so installation stays straightforward and the finished look is achievable without extra trips to the store.
• Attaches without drilling into the post - preserves the structural integrity of the post and simplifies the installation process, making it practical for both new builds and retrofit applications over existing post bases.
• Made from black composite plastic - provides a durable, weather-resistant decorative finish suited to outdoor environments while maintaining a consistent, uniform color that coordinates with other Outdoor Accents Mission Collection hardware.
• Sized for nominal 6x6 post bases - designed specifically to fit standard 6x6 framing dimensions, ensuring a proper, snug fit rather than a generic cover that requires adjustment or modification.

Why This Product

• Hides utility, adds style - post base hardware is essential for structural connection but rarely attractive; this decorative wrap conceals that hardware entirely, giving outdoor structures a custom, intentional appearance without compromising the underlying connection.
• No-drill installation protects your post - because the cover assembles around the outside of the post base and fastens to itself rather than to the post, there is no need to bore into the post, keeping the wood intact and the project clean.
• Everything needed is in the box - the four-piece plate set and the twelve black screws required for assembly are all included, so buyers can move directly from unboxing to installation without sourcing additional components.
• Broad post base compatibility makes it a versatile finishing solution - with verified compatibility across five Simpson post base models, this cover works across a wide range of deck and pergola framing scenarios, reducing the need to shop for multiple decorative solutions on a single project.
