The Simpson ECC76 End Column Cap from Simpson is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections in wood construction. Designed specifically for a 6-3/4 in. beam and 6X post configuration, this end column cap features a seat that extends beyond one side of the column, providing additional bearing surface area to effectively distribute load from the beam to the post. Built from 3-gauge steel and finished in Simpson Strong-Tie gray paint, the ECC76 delivers the structural integrity and precision fit that heavy timber framing applications demand.

Key Features

• End-of-beam seat design - extends beyond one side of the column to increase bearing surface area, improving load distribution and connection reliability at end-of-beam locations
• 3-gauge steel construction - provides the strength and rigidity needed to handle demanding structural loads in heavy timber framing applications
• Simpson Strong-Tie gray paint finish - offers a consistent, durable coating that is ready for installation in typical wood construction environments
• Certified welds - deliver confidence in connection strength and loading performance, supporting predictable, code-consistent structural behavior
• Increased uplift load capacity - addresses the additional forces introduced by earthquake or wind loading, making this cap suitable for structures in high-load regions
• NDS code-compliant bolt spacing - ensures fastener placement meets code requirements, simplifying inspection and approval on wood framing projects
• Configurable strap orientation - straps may be rotated 90 deg. to accommodate varied framing conditions without requiring a custom part

Why This Product

• Purpose-built fit for 6X post and 6-3/4 in. beam combinations - the ECC76 is dimensioned specifically for this pairing, eliminating guesswork and reducing the risk of fit issues during installation on heavy timber framing projects
• Engineered for high-demand structural conditions - with increased uplift load capacity and certified welds, this end column cap is a dependable choice for connections subject to seismic or wind uplift forces
• Domestic manufacturing - produced in the United States, reflecting Simpson's commitment to quality control and consistent production standards
• Flexible configuration options - strap rotation and the ability to specify custom lumber dimensions mean this connector can adapt to non-standard framing scenarios without sacrificing structural performance

Frequently Asked Questions

What beam and post sizes is the ECC76 designed to fit?

The ECC76 is designed specifically for a 6-3/4" beam and a 6X post configuration, making it suitable for heavy timber framing applications that use these dimensions.

What fasteners are required to install the ECC76?

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

What makes the ECC76 an "end" column cap rather than a standard column cap?

The ECC76 is designed for end-of-beam applications, meaning its seat extends beyond one side of the column to provide additional bearing surface area. This extended seat distributes the beam load beyond one side of the column, which is the defining characteristic of an end column cap as opposed to a centered column cap.

What material and finish is used on the ECC76?

The ECC76 is constructed from 3-gauge steel and finished with Simpson Strong-Tie gray paint, providing heavy-duty strength and corrosion resistance for demanding structural applications.
