The Simpson Strong-Tie ECC86 End Column Cap is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction. Designed for use with an 8x beam and 6x post, this end column cap features a seat that extends beyond one side of the column, providing additional bearing surface area that effectively distributes load from the beam while delivering critical support at the connection point. Built from 3-gauge steel and finished in Simpson Strong-Tie gray paint, the ECC86 is a heavy-duty hardware solution trusted for structural integrity in demanding construction environments.

Frequently Asked Questions

What beam and post sizes is the ECC86 designed to fit?

The ECC86 is specifically designed for use with an 8x beam and a 6x post, making it suitable for heavy-duty column-to-beam connections where those lumber dimensions are used.

What fasteners are required to install the ECC86?

Installation requires 3/4" machine bolts - two for the beam and two for the post. The bolt spacing is designed to meet NDS code requirements for optimal performance.

What makes the ECC86 suitable for end-of-beam applications specifically?

The ECC86 features an extended seat that goes beyond one side of the column, providing additional bearing surface area. This design effectively distributes load from the beam and supports the connection at end-of-beam locations, where a standard centered cap would not be appropriate.

What material and finish is used on the ECC86, and is it rated for elevated uplift loads?

The ECC86 is constructed from 3-gauge steel and finished in Simpson Strong-Tie gray paint. It features certified welds and is engineered with increased uplift load capacity, making it suitable for applications subject to elevated uplift loads such as those caused by earthquake or wind forces.
