The Simpson End Column Cap with Uplift 3/4 Inch Bolt is an engineered connector built for column-beam connections in end-of-beam applications where uplift resistance is a structural requirement. The seat of the column cap provides additional surface area for bearing that extends beyond one side of the column, helping to distribute load from the beam and deliver reliable support at the connection point. Designed with flexibility in mind, this cap accommodates a range of installation configurations and lumber dimensions, making it a practical solution for structural framing projects that demand both strength and adaptability.

Key Features

• End-of-beam column cap design with uplift capacity - engineered specifically for end-of-beam applications requiring uplift values, so the connection performs reliably under both downward and lifting forces.
• Extended seat with additional bearing surface area - the seat extends beyond one side of the column, distributing beam load more evenly across the connection and reducing stress concentration at the joint.
• 3/4 inch bolt fastening - provides a secure, fixed connection point that anchors the cap firmly to the column and supports the uplift resistance the connector is designed to deliver.
• Rotatable strap orientation - straps may be rotated 90 deg., giving installers the flexibility to adapt the connector to different framing layouts and on-site conditions.
• Custom and rough-cut lumber compatibility - dimensions can be provided for special, custom, or rough-cut lumber sizes, and an optional W2 dimension may be specified, so the cap can be configured to fit non-standard framing scenarios.

Why This Product

• Purpose-built for uplift-critical connections - where standard column caps fall short, this connector is specifically engineered for end-of-beam positions that require verified uplift resistance, directly addressing a common structural challenge in covered structures, decks, and similar framing applications.
• Better load distribution at the beam end - the extended seat bearing surface reduces concentrated stress at the column top, supporting a more stable and durable connection over the life of the structure.
• Adaptable to real-world installation conditions - with strap rotation flexibility and support for custom lumber dimensions, this cap works across a wider range of framing situations without requiring a different product or workaround.
• Configurable to fit non-standard framing - the ability to specify an optional W2 dimension means the connector is not limited to off-the-shelf lumber sizes, making it a practical choice for projects involving rough-cut or specialty timber.

Frequently Asked Questions

What is the ECCU 3/4 designed to do?

The ECCU 3/4 is designed for column-beam connections in end-of-beam applications that require uplift values. It helps distribute the load from the beam and provides structural support at the connection point.

How does the seat design benefit the connection?

The seat of the column cap provides additional surface area for bearing that extends beyond one side of the column, improving load distribution and connection stability.

Can the straps be repositioned for different installation orientations?

Yes. Straps may be rotated 90 deg., offering flexibility for various installation configurations.

Is this product available for custom or rough-cut lumber sizes?

Yes. For special, custom, or rough-cut lumber sizes, dimensions can be provided. An optional W2 dimension may be specified; however, the W2 dimension on straps rotated 90 deg. is limited by the W1 dimension.
