Simpson Strong Tie CPS6 6x6 Post Standoff Base

Product Description

The SIMPSON STRONG TIE CPS6 is a composite standoff post base designed for 6x6 post and column installations where moisture management at the base connection is critical. The composite construction maximizes concrete contact area while preventing moisture accumulation at the post-to-ground interface, satisfying the required 1 inch standoff clearance that helps preserve wood integrity over time. The CPS6 is installed using a 5/8 inch anchor bolt and four 10D nails, making it a straightforward retrofit or new-construction fastener for licensed contractors and experienced builders alike.

This standoff base is suited for residential and light commercial construction applications where 6x6 posts or columns are anchored to concrete pads, footings, or slabs. Typical installations include deck posts, covered porch columns, carport supports, and structural framing connections. The corrosion-resistant composite material makes it appropriate for use in high-moisture, coastal, or chemically treated lumber environments where metal hardware may be more susceptible to degradation.

Key Features

• Composite construction provides outstanding corrosion resistance in demanding environments
• Maximizes concrete contact area for solid, stable base support
• Built-in 1 inch standoff clearance meets code requirements for post-base separation
• Installs with a single 5/8 inch anchor bolt and four 10D nails
• Sized specifically for 6x6 post and column applications

Compatibility

Designed as an OEM-style replacement and new-installation post base for 6x6 structural posts and columns anchored to concrete footings or slabs in residential and light commercial framing applications.

Installation Notes

Installation of the CPS6 should be performed by a qualified contractor familiar with applicable building codes, including IBC and IRC provisions for post-base connections. Anchor bolt placement in the concrete footing must be set before the pour or drilled and epoxy-set after cure. Ensure the concrete surface is clean and level before seating the base. Do not substitute anchor bolt size or nail schedule without consulting the manufacturer load tables and local code requirements.
