The Simpson End Column Cap with Uplift - ECCU 5/8 is an engineered connector designed for column-beam connections in end-of-beam applications where uplift resistance is required. The cap's seat extends beyond one side of the column, providing additional bearing surface area that helps distribute beam loads efficiently while delivering reliable uplift support for the connection. Featuring a 5/8" bolt configuration, the ECCU 5/8 delivers a reliable, demanding-duty structural connection.

Key Features

• End-of-Beam Design: Engineered specifically for column-beam connections in end-of-beam applications.
• Uplift Resistance: Provides reliable uplift values critical for structural integrity in demanding load conditions.
• Extended Seat Bearing Surface: The seat extends beyond one side of the column to increase the bearing area and improve load distribution.
• Load Distribution: Helps distribute the load from the beam and provides solid support for the overall connection.
• 5/8" Bolt Configuration: Designed around a 5/8" bolt for secure and consistent fastening performance.
• Custom, Made-to-Order: Configurable for special, custom, or rough-cut lumber sizes to suit unique project requirements.

Frequently Asked Questions

What type of structural application is the ECCU 5/8 designed for?

The ECCU 5/8 is engineered specifically for column-to-beam connections in end-of-beam applications where uplift resistance is required. It is not intended for standard mid-beam column cap installations, making it the appropriate choice when the beam terminates at the column rather than passing over it.

What makes the ECCU 5/8 different from a standard column cap?

Unlike a standard column cap, the ECCU 5/8 features an extended seat that projects beyond one side of the column. This extended bearing surface increases the load distribution area and provides the uplift resistance values needed for demanding structural connections at end-of-beam conditions.

Can the ECCU 5/8 be used with custom or rough-cut lumber sizes?

Yes. The ECCU 5/8 is a custom, made-to-order product that can be configured to accommodate special, custom, or rough-cut lumber sizes, making it suitable for projects where standard dimensional lumber sizes are not being used.

Is the ECCU 5/8 returnable after purchase?

No. Because the ECCU 5/8 is a custom, made-to-order product, it is non-returnable. It is important to confirm all project specifications - including bolt size, lumber dimensions, and connection requirements - before placing an order.
