The Simpson Strong-Tie ECC78 End Column Cap is engineered to deliver robust column-to-beam connections in end-of-beam applications throughout wood construction projects. Designed specifically for use with a 6-3/4" beam and an 8X post, this end column cap features a seat that extends beyond one side of the column, providing an expanded bearing surface area that helps distribute load efficiently from the beam while reinforcing the overall connection. Constructed from heavy-duty 3-gauge steel and finished in Simpson Strong-Tie gray paint, the ECC78 is built to perform under demanding structural conditions, including elevated loads associated with seismic and wind events.

Key Features

• Certified Welds: Certified welds provide confidence in strength and loading performance throughout the life of the connection.
• Enhanced Uplift Capacity: Uplift loads are increased to address earthquake or wind loading requirements, making this cap suitable for high-demand structural environments.
• NDS-Compliant Bolt Spacing: Bolt spacing meets NDS code requirements to ensure optimal performance and code-compliant installations.
• Diamond Holes: Diamond holes are incorporated into the design to allow for convenient temporary fastening during installation.
• Extended Bearing Seat: The seat of the column cap provides additional surface area of bearing that extends beyond one side of the column, helping to distribute beam loads effectively.
• Heavy-Gauge Construction: Fabricated from 3-gauge steel for exceptional durability and structural integrity.
• Domestic Manufacturing: Made in the United States.
