Product Description
The Simpson 6 x 6 Black Composite-Plastic Standoff Post Base from Simpson is an engineered composite-plastic standoff base built for use with a nominal 6x6 post or column in both indoor and outdoor applications. It attaches to the bottom of a solid wood column and anchors to concrete using threaded rod and epoxy, creating a code-required 1-inch standoff that helps protect the base of the post from ground moisture and the deterioration it causes. The bold black finish delivers a clean, custom appearance that complements a wide range of architectural column installations.
Key Features
- Fits nominal 6x6 post or column - sized precisely for a standard 6x6 member, so there is no guesswork or field modification required at installation.
- Code-required 1-inch standoff - elevates the base of the wood column off the concrete surface to reduce moisture contact, helping extend the usable life of the post.
- Engineered composite plastic construction - resists corrosion and moisture in a way that traditional metal hardware cannot, making it well suited for exposed outdoor column bases and covered interior applications alike.
- Black finish for a custom look - provides a finished, architectural appearance that integrates cleanly with decorative column systems rather than drawing attention to the hardware.
- Attaches to concrete with threaded rod and epoxy - delivers a secure, load-rated connection to the concrete substrate, giving the column base the structural integrity required for permanent installations.
Why This Product
- Load-rated for confidence in structural applications - the CPS series is load rated, meaning the standoff base has been engineered and tested to perform under real structural demands, not simply used as a decorative cap.
- Composite plastic outperforms metal in wet environments - because the base is made from engineered composite plastic rather than steel, it will not rust or corrode when exposed to moisture, making it a practical long-term choice for outdoor porches, pergolas, and covered entries.
- Designed to satisfy code requirements out of the box - the built-in 1-inch standoff meets code requirements for post-base elevation without needing shims, spacers, or field fabrication.
- Versatile indoor and outdoor use - whether the installation is a finished interior space or an exposed exterior application, this standoff base is engineered to perform reliably in both environments.
