The Simpson ECC6-7 1/8 6X Beam 7 Inch Post End Column Cap is an engineered heavy-duty connector from Simpson built to deliver reliable column-to-beam connections in end-of-beam applications within wood construction. Designed specifically for use with a 6X beam and a 7 inch post, this end column cap features a seat that extends bearing surface beyond one side of the column, helping to distribute structural loads effectively across the connection point. Constructed from 7-gauge steel and finished with Simpson gray paint, this column cap is purpose-built for demanding post-and-beam framing projects where structural integrity and code compliance are non-negotiable.

Key Features

• Certified Welds - Welds are certified for strength and load performance, giving builders and inspectors confidence in the integrity of every connection.
• Enhanced Uplift Capacity - Engineered with increased uplift load resistance, making this cap well-suited for seismic (earthquake) and high-wind zone applications where extra holding power matters.
• NDS Code-Compliant Bolt Spacing - Bolt spacing meets National Design Specification requirements, supporting smooth project approvals and structural plan reviews.
• Heavy-Gauge Steel Construction - Formed from 7-gauge steel, this column cap provides the rigidity and durability required for structural post-and-beam connections under sustained load.
• Simpson Gray Paint Finish - The factory-applied finish provides a consistent, professional appearance and baseline surface protection appropriate for interior structural applications.
• End-of-Beam Application Design - The extended bearing seat is specifically configured for end column cap use, providing load distribution where a standard cap would leave performance gaps.

Why This Product

• Built for high-load structural connections - The combination of 7-gauge steel construction and certified welds means this column cap is engineered to handle the real demands of post-and-beam framing, not just light-duty applications.
• Engineered for seismic and wind-load zones - With uplift loads specifically increased to address earthquake and wind forces, this cap is a practical choice for projects in regions where lateral and uplift resistance are code requirements.
• Exact-fit design for 6X beam and 7 inch post applications - Rather than adapting a general-purpose connector, this cap is purpose-matched to 6X beam and 7 inch post dimensions, reducing installation guesswork and helping ensure a code-compliant fit.
• Domestic manufacturing from Simpson - Backed by Simpson's engineering standards and produced in the United States, this end column cap is a trusted option for contractors and structural engineers who need consistent, verifiable quality on every job.
