Product Description
The Simpson 4 x 6 Black Composite-Plastic Standoff Post Base from Simpson is a load-rated standoff base engineered for use with nominal 4x6 posts and columns in both indoor and outdoor settings. It attaches directly to the bottom of a solid wood column and anchors to concrete using threaded rod and epoxy, delivering the code-required 1-in. standoff that keeps wood elevated above the concrete surface. Its engineered composite plastic construction and black finish make it a practical and clean-looking solution for deck posts, porch columns, pergola supports, and similar structural applications.
Key Features
- Designed for nominal 4x6 posts and columns - ensures a proper, secure fit without modification or guesswork during installation.
- Provides code-required 1-in. standoff - keeps the base of the wood post elevated above the concrete surface, helping protect the wood from moisture contact and meeting building code requirements.
- Engineered composite plastic construction - resists rust and corrosion, making this post base a reliable choice for exposed exterior environments as well as interior applications.
- Black finish - delivers a clean, custom appearance that blends well with a wide range of column styles and architectural finishes.
Why This Product
- Code compliance built in - the 1-in. standoff is not just a design detail; it meets code requirements for wood-to-concrete connections, reducing the need for additional hardware or workarounds on your project.
- Rated for real structural loads - the CPS series is load rated, giving contractors and builders confidence that the connection is engineered to perform, not just to fit.
- Indoor and outdoor versatility - composite plastic construction handles the demands of exterior exposure without rusting, making this standoff base equally useful on a covered interior floor or an open exterior slab.
- Concrete-anchored security - the threaded rod and epoxy anchoring method creates a firm, stable connection between the post base and the concrete footing, supporting the structural integrity of decks, porches, and other column-supported structures.
