The Simpson ECC98 End Column Cap is a heavy-duty connector engineered for end-of-beam column-to-beam connections in wood construction. Built by Simpson from 3-gauge steel with a gray paint finish, this cap is sized specifically for 8-3/4 in. beams paired with 8x posts. Its extended seat design provides additional bearing surface area at the column-beam interface, helping distribute load effectively and reinforce the connection where structural integrity matters most.

Key Features

• Extended seat beyond one side of the column - provides additional bearing surface area at the column-beam interface, improving load distribution in end-of-beam applications
• Heavy-duty 3-gauge steel construction - delivers the material strength needed to handle demanding structural connections in wood framing
• Certified welds - give builders confidence in connection strength and published load values
• Increased uplift load capacity - supports structural connections in high-demand conditions such as earthquake and wind loading scenarios
• Bolt spacing meets NDS code requirements - helps ensure compliance in permitted and engineered wood construction projects
• Simpson gray paint finish - provides a consistent, professional appearance suited to structural hardware applications

Why This Product

• Purpose-built fit for 8-3/4 in. beams and 8x posts - eliminates guesswork by offering a connector sized and rated specifically for this beam-and-post combination, reducing the risk of mismatched hardware in critical end-column connections
• Engineered for seismic and wind uplift demands - the ECC98 is approved for structural connections requiring increased uplift capacity, making it a sound choice for projects in regions subject to earthquake or high-wind building codes
• Backed by a trusted structural hardware brand - Simpson is a recognized name in engineered wood connectors, and the ECC98 carries certified welds and NDS-compliant bolt spacing to support inspections and engineer approvals
• Domestically produced structural connector - the ECC98 is a product of the United States, which can be relevant for projects with domestic-sourcing requirements or quality expectations tied to U.S. manufacturing standards

Frequently Asked Questions

What beam and post sizes is the ECC98 designed to work with?

The ECC98 is designed specifically for use with 8-3/4" beams and 8X posts, making it suited for end-of-beam column-to-beam connections in wood construction.

What fasteners are required to install the ECC98?

Installation requires 3/4" machine bolts - 4 bolts for the beam connection and 2 bolts for the post connection.

What makes the ECC98 different from a standard column cap?

The ECC98 features an extended seat that reaches beyond one side of the column, providing additional bearing surface area to better distribute load from the beam. It is designed specifically for end-of-beam applications rather than interior or mid-span column positions.

What material and finish is used on the ECC98?

The ECC98 is constructed from heavy-duty 3-gauge steel and finished with Simpson Strong-Tie gray paint, providing durability for demanding structural environments.
