The Simpson End Column Cap with Uplift 5/8 in Bolt ECCU 5/8 is an engineered structural connector designed for column-to-beam connections in end-of-beam applications where uplift resistance is a requirement. Unlike standard column caps intended for mid-beam installations, this connector is built specifically for locations where the beam terminates at the column, with a seat that extends beyond one side of the column to provide additional bearing surface area for efficient load distribution. The 5/8 in. bolt configuration delivers a dependable, heavy-duty connection suited to structural applications where both vertical load transfer and engineered uplift values are critical.

Key Features

• End-of-Beam Configuration - Engineered specifically for column-to-beam connections where the beam terminates at the column rather than passing over it, ensuring the correct connector is used for the right structural condition.
• Uplift Resistance - Provides engineered uplift values at the connection point, giving builders and engineers the confidence needed for structurally demanding load conditions where standard caps fall short.
• Extended Seat Bearing Surface - The seat extends beyond one side of the column, distributing beam loads across a greater surface area and improving overall connection performance.
• 5/8 in. Bolt Size - The 5/8 in. bolt configuration supports a robust, reliable connection suited to heavy structural framing applications.
• Configurable Strap Orientation - Straps may be rotated 90 deg., offering installation flexibility to accommodate varying framing layouts and project conditions.
• Custom and Rough-Cut Lumber Compatibility - Accommodates custom or rough-cut lumber dimensions, and an optional W2 dimension may be specified, making this connector adaptable to non-standard framing scenarios.

Why This Product

• Purpose-Built for End-of-Beam Structural Connections - This connector is designed exclusively for end-of-beam column-to-beam applications, so buyers can be confident they are specifying the correct hardware for a connection type that standard column caps are not intended to handle.
• Uplift Resistance Built Into the Design - Because the ECCU 5/8 delivers engineered uplift resistance, it is well-suited for projects where wind uplift or other tension forces at the connection must be accounted for in the structural design.
• Adaptable to Project-Specific Requirements - With configurable strap orientation and compatibility with custom and rough-cut lumber sizes, this connector works across a broader range of framing conditions without requiring a completely different product.
• Engineered for Reliability in Demanding Applications - The extended seat bearing surface and 5/8 in. bolt configuration combine to support heavy load transfer at the column-to-beam interface, providing a structurally sound solution for projects where connection integrity cannot be compromised.

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.
