The Simpson Black Column Cap for 5-1/8 in. Beam and 8X Post is a heavy-duty structural connector from Simpson built for indoor architectural wood construction where a clean, refined look and proven structural performance are both required. Part of the Simpson Classic Collection, this column cap features smooth edges and clean lines that make it well-suited for visible column-to-beam connections, while its extended seat provides additional bearing surface beyond each side of the column to help distribute load and improve connection stability.

Key Features

• Extended seat bearing surface - projects beyond each side of the column to distribute beam load more effectively, improving stability at the connection point
• 3 gauge steel construction - provides the heavy-duty thickness needed to handle demanding structural loads at column-to-beam connections
• Black powder-coat finish - delivers a sleek, consistent appearance that suits visible architectural applications where hardware aesthetics matter
• Classic Collection design with smooth edges and clean lines - integrates naturally into interior architectural settings without detracting from the finished look of the space
• Certified welds - ensure connection integrity is verifiable and consistent, giving builders and inspectors confidence in structural performance
• Sized for 8X posts and 5-1/8 in. beams - purpose-fit dimensions eliminate guesswork and ensure the cap seats correctly with no modification required
• Approved for applications subject to earthquake or wind uplift loading - suitable for projects with lateral force requirements, broadening its use across code-sensitive builds
• NDS code-compliant bolt spacing - fastener layout meets National Design Specification requirements, simplifying permitting and inspection on structural projects

Why This Product

• Form and function in one connector - the black powder-coat finish and Classic Collection styling mean this cap works in exposed structural applications without requiring cover-up trim or additional finishing work
• Built for code-sensitive structural projects - approval for earthquake and wind uplift loading, combined with NDS-compliant bolt spacing, makes this column cap a dependable choice where engineered performance documentation matters
• Precision fit for specific lumber dimensions - designed specifically for 8X posts and 5-1/8 in. beams, so the connection is secure and properly seated without field modifications
• American-made quality from a trusted connector brand - produced by Simpson, a recognized name in structural connectors, with certified welds that support consistent, verifiable performance across projects

Frequently Asked Questions

What post and beam sizes is the CC5 1/4-8PC designed to fit?

The CC5 1/4-8PC is designed for use with an 8X post and a 5-1/8" beam, making it suitable for projects that require a connection between those specific lumber dimensions.

What fasteners are required to install this column cap?

Installation requires (4) 5/8" machine bolts for the beam and (2) 5/8" machine bolts for the post. The bolt spacing is designed to meet NDS code requirements for optimal performance.

Is this column cap suitable for outdoor use?

The CC5 1/4-8PC is purpose-built for indoor architectural applications. Its black powder-coat finish is intended for visible, decorative use where a refined appearance is important, but it is specified for indoor use rather than exterior exposure.

How does the seat design of this column cap improve structural performance?

The seat of the column cap extends beyond each side of the column, providing additional surface area for bearing. This helps distribute the load from the beam more effectively and adds support and stability to the overall connection.
