Product Description
The Simpson 4X Adjustable Post Cap in Stainless Steel is an engineered structural connector from Simpson designed to create a positive, reliable connection between a beam and a post. Built from 18-gauge stainless steel, this adjustable post cap is well-suited for demanding exterior environments where corrosion resistance is critical - from coastal decks to exposed pergolas. The AC series is designed to be installed in pairs and supports both new construction and retrofit applications where a secure, load-bearing post-to-beam connection is required.
Key Features
- Eliminates nailing into end grains - reduces the risk of splitting and delivers a cleaner, more structurally sound installation compared to traditional fastening methods
- Stronger than angled nailing or screw fastening - provides a more reliable structural connection, giving builders and homeowners greater confidence in long-term performance
- Designed for nominal 4x lumber - ensures a proper fit with standard 4x posts, removing guesswork and simplifying installation
- 18-gauge stainless-steel construction - delivers high and severe corrosion resistance, making this connector a dependable choice for harsh or high-moisture outdoor environments
- Adjustable design - accommodates variability in post and beam alignment, making it practical for both new builds and retrofit projects
Why This Product
- Built for corrosive environments - stainless-steel construction provides high and severe corrosion resistance, so this post cap holds up where standard steel connectors are prone to deterioration over time
- A stronger alternative to traditional fastening - by eliminating end-grain nailing and outperforming angled nailing or screw fastening, this connector offers a structurally superior post-to-beam connection
- Versatile for new construction and retrofit use - the adjustable design works with existing posts and beams as well as fresh installations, reducing the need for additional hardware or custom solutions
- Paired installation ensures balanced load distribution - AC series connectors are engineered to be installed in pairs, which distributes structural load properly and meets the design intent of the connector for a safe, code-conscious build

Frequently Asked Questions
- What is the purpose of the Simpson AC4SS post cap?
- The AC4SS is designed to provide a positive connection between a beam and a post, connecting the tops of posts to members for a secure structural connection. It is ideal for both new construction and retrofit applications where structural support is needed.
- Why must AC series post caps always be installed in pairs?
- AC series connectors are engineered to work as a pair to ensure a balanced and structurally sound connection between the post and beam. Installing them in pairs distributes load properly and meets the design intent of the connector.
- What fasteners are required to install the AC4SS post cap?
- The AC4SS should be installed with 0.162 in. x 3-1/2 in. stainless-steel nails to maintain compatibility with the stainless-steel construction and preserve corrosion resistance.
- Why is stainless steel important for this post cap?
- The stainless-steel construction of the AC4SS provides high and severe corrosion resistance, making it well-suited for harsh exterior environments where standard steel connectors may be prone to deterioration over time.
