The Simpson ECCQ88SDS2.5 End Column Cap from Simpson Strong-Tie is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction. Sized for nominal 8x beams and 8x posts, this connector features a seat that extends beyond the side of the column, providing an additional bearing surface that helps distribute load from the beam and support the connection under real structural demands. Built from 3-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, it arrives complete with 28 Strong-Drive SDS Heavy-Duty Connector screws - 14 for the beam and 14 for the post - so installation is ready to begin straight out of the box.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included (28 total) - Replaces through-bolt installations with a lower-profile fastener that attaches to a greater net section area of the column, resulting in a faster, cleaner installation without sacrificing connection strength.
• Extended seat bearing surface - The seat reaches beyond the side of the column, helping distribute beam loads more evenly and providing added support at the connection point in end-of-beam applications.
• Certified welds - Every weld is certified, giving builders and inspectors documented confidence in the strength and load-carrying capacity of the connector.
• Increased uplift load ratings - Uplift values have been raised to meet the demands of earthquake and wind loading, making this cap a dependable choice for structurally critical connections in high-load environments.
• Diamond holes for temporary fastening - Allows installers to tack the cap in place during positioning before final fastening, reducing the chance of misalignment and speeding up the installation process.
• 3-gauge steel construction - Heavy-gauge material provides the rigidity and durability required for demanding structural column-to-beam connections in wood framing.
• Simpson Strong-Tie gray paint finish - Provides a clean, consistent appearance and a baseline level of surface protection appropriate for the connector's intended structural applications.

Why This Product

• Everything needed for installation is included - The 28 Strong-Drive SDS screws ship with the connector, eliminating a separate fastener purchase and ensuring the right hardware is always paired with the right cap.
• Designed specifically for end-of-beam column connections - Unlike general-purpose brackets, the ECCQ is purpose-built for end-of-beam applications, with a seat geometry that addresses the unique load distribution challenges those connections present.
• Engineered for high-load and code-sensitive projects - Certified welds, increased uplift ratings, and 3-gauge steel construction make this connector well suited for structural applications where earthquake or wind loading requirements must be met.
• Faster installation without compromising performance - SDS screw attachment is quicker than traditional through-bolt methods and engages a greater net section area of the column, delivering both jobsite efficiency and strong structural performance in a single solution.
