The Simpson Strong-Tie ECC88 End Column Cap is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction. The seat of the column cap provides an additional surface area of bearing that extends beyond one side of the column, helping to distribute the load from the beam while providing robust support for the connection. Built to exacting standards and finished with Simpson Strong-Tie gray paint, the ECC88 is a trusted solution for contractors and builders requiring dependable structural performance at column-beam junctions.

Key Features

Frequently Asked Questions

What beam and post sizes is the ECC88 designed to fit?

The ECC88 End Column Cap is designed for use with 8x beams and 8x posts, making it specifically suited for column-to-beam connections using nominal 8-inch lumber in both orientations.

What fasteners are required to install the ECC88?

The ECC88 requires two 3/4-inch machine bolts for the beam connection. Bolt spacing is designed to meet NDS code requirements to ensure optimal structural performance.

What makes the ECC88 suitable for end-of-beam applications specifically?

The ECC88 features an extended bearing surface where the cap seat extends beyond one side of the column. This design improves load distribution from the beam to the post, making it well-suited for end-of-beam column connections rather than interior mid-span locations.

What material and finish is the ECC88 made from?

The ECC88 is fabricated from 3-gauge steel for heavy-duty strength and durability, and it is finished with Simpson Strong-Tie gray paint. It also features certified welds to provide confidence in its strength and load capacity.
