The Simpson ECC88PC Black End Column Cap is purpose-built for end-of-beam column-to-beam connections in wood construction, delivering reliable structural performance where an 8x beam meets an 8x post. Engineered by Simpson, this heavy-duty column cap features a seat that extends beyond one side of the column, creating an additional bearing surface that distributes load from the beam to the post with confidence. Its black powder-coat finish and 3-gauge steel construction make it a dependable choice for heavy timber framing applications where structural integrity and code compliance are essential.

Key Features

• End-of-beam seat design - extends beyond one side of the column to provide an additional bearing surface, ensuring effective load distribution from beam to post at end applications
• 3-gauge steel construction - delivers the heavy-duty strength needed for demanding structural connections in wood framing projects
• Certified welds - give installers and inspectors confidence in strength and loading performance at every connection point
• Increased uplift load capacity - engineered to resist forces caused by seismic activity and high-wind loading, making it suitable for projects in challenging environmental conditions
• Black powder-coat finish - provides a clean, consistent appearance well suited to exposed timber framing and architectural applications
• NDS code-compliant fastener bolt spacing - supports compliance requirements for wood construction projects, reducing friction during inspection and approval
• Configurable strap rotation - straps may be rotated 90 deg., offering installation flexibility to suit varying jobsite conditions and connection orientations

Why This Product

• Designed specifically for 8x timber connections - precisely sized for 8x beam and 8x post configurations, this end column cap eliminates the guesswork of adapting a general-purpose connector to heavy timber framing and ensures a proper, secure fit from the start
• Dual uplift resistance for high-risk environments - engineered capacity to resist both seismic and high-wind uplift forces means this connector is ready for structurally demanding applications where safety margins cannot be compromised
• American-made quality from a trusted structural connector brand - produced by Simpson with certified welds and 3-gauge steel, this cap reflects the rigorous manufacturing standards the brand is known for in professional wood construction
• Flexible configuration for complex installations - with strap rotation up to 90 deg. and the option to specify custom lumber dimensions, this column cap adapts to a wider range of project conditions without requiring a custom-fabricated solution

Frequently Asked Questions

What beam and post sizes is the ECC88PC designed to fit?

The ECC88PC is designed specifically for 8x beam and 8x post configurations, making it suitable for heavy timber framing applications that use standard dimensional 8x lumber.

What fasteners are required to install the ECC88PC?

Installation requires 3/4" machine bolts - two for the beam connection and two for the post connection, for a total of four bolts.

What makes the ECC88PC suitable for end-of-beam applications?

The ECC88PC features an extended seat design that extends beyond one side of the column, providing an additional bearing surface area that distributes load from the beam at end-of-beam locations where a standard centered cap would not be appropriate.

Is the ECC88PC built to handle seismic or high-wind conditions?

Yes. The ECC88PC is engineered with increased uplift load capacity specifically for earthquake or wind loading conditions. It is also constructed from heavy-duty 3-gauge steel with certified welds and features NDS code-compliant bolt spacing to ensure reliable structural performance in demanding applications.
