The Simpson Strong-Tie ECCQ84SDS2.5 is a heavy-duty end column cap engineered to deliver reliable, high-strength column-to-beam connections in end-of-beam wood construction applications. Designed for 8x beams and 4x post ends, this connector features an extended seat that provides additional bearing surface area beyond the side of the column, helping to effectively distribute load transfer from the beam. Fabricated from 3-gauge steel with a Simpson Strong-Tie Gray paint finish and manufactured in the United States, the ECCQ84SDS2.5 arrives complete with Strong-Drive SDS Heavy-Duty Connector screws for a fast, secure, and low-profile installation.
Key Features
- Extended seat bearing surface distributes beam load beyond the column side for superior support
- Strong-Drive SDS Heavy-Duty Connector screws provide a lower profile than standard through bolts
- SDS screws attach to a greater net section area of the column than bolt attachment typically allows
- Certified welds deliver confidence in strength and consistent load performance
- Increased uplift load values designed to meet earthquake and wind loading demands
- Diamond holes allow for temporary fastening during installation
- Heavy 3-gauge steel construction for long-term structural integrity
- Simpson Strong-Tie Gray paint finish for durability

Frequently Asked Questions
- What beam and post sizes is the ECCQ84SDS2.5 designed to fit?
- This end column cap is designed for use with 8x beams and 4x post ends. The beam width dimension is 71/2 inches, W1 is 71/2 inches, and W2 is 3-5/8 inches, confirming compatibility with standard dimensional lumber in those sizes.
- What fasteners are included, and why are they preferred over standard bolts?
- The ECCQ84SDS2.5 includes Strong-Drive SDS Heavy-Duty Connector screws. These screws are preferred over standard through bolts because they provide a lower profile installation and attach to a greater net section area of the column, resulting in strong, reliable connections without the bulk of traditional bolt hardware.
- What is the overall size of this column cap?
- The ECCQ84SDS2.5 measures 81/2 inches in length (L) and 7 inches in height (H), with a beam width (W1) of 71/2 inches and a W2 dimension of 3-5/8 inches. It is constructed from heavy 3-gauge steel with a Simpson Strong-Tie Gray paint finish.
- Is this connector suitable for high-wind or seismic conditions?
- Yes. The ECCQ84SDS2.5 features increased uplift load values specifically designed to meet the demands of earthquake and wind loading, making it appropriate for construction in regions subject to those structural requirements.
