Product Description
The Simpson Strong-Tie ECCLL666HDG is an L-Shape End Column Cap engineered to provide strong, reliable column-to-beam connections in end-of-beam applications where two beams intersect in an "L" formation on top of a column. Designed for 6x main beam, 6x post, and 6x side beam nominal member sizes, this skewed-left cap helps distribute load from the beams and delivers dependable structural support at the connection point. Fabricated from 7-gauge steel with a hot-dip galvanized (HDG) finish, the ECCLL666HDG is built for long-term performance in exterior environments and applications involving treated wood. Assembled with certified welds and engineered bolt spacing that meets NDS code requirements, this column cap delivers confidence in both strength and code compliance.

- The download shall be determined from the allowable loads for the unmodified product (see ECC column caps). The side beam can take a maximum of 40% of the download and shall not exceed 10,665 lb. The sum of the loads for the side beam(s) and main beam cannot exceed the table load.
- Uplift loads do not apply for ECCL caps.
- The column width in the direction of the main beam width must be the same as the main beam width (W1).
Frequently Asked Questions
- What beam and post sizes is the ECCLL666HDG designed to fit?
- The ECCLL666HDG is sized for nominal 6x main beam, 6x post, and 6x side beam members. It is engineered specifically for end-of-beam applications where two beams intersect in an "L" formation on top of a column.
- Is this column cap suitable for exterior use or applications with treated wood?
- Yes. The ECCLL666HDG features a hot-dip galvanized (HDG) finish, which provides extra corrosion resistance making it well suited for exterior environments and applications involving pressure-treated wood.
- What fasteners are required to install this column cap?
- The ECCLL666HDG should be installed with 5/8-inch diameter bolts. The bolt spacing is engineered to meet NDS code requirements to ensure optimal performance at the connection.
- Is this cap available in a right-hand orientation, and how does the left orientation differ?
- The ECCLL666HDG is a skewed-left column cap. If your project requires a right-direction orientation, you should order the ECCLR model instead. The two versions are mirror images of each other and are not interchangeable, so it is important to confirm the correct direction for your specific application before ordering.
