The Simpson ECCQ88SDS2.5ROT is a heavy-duty ECCQ Rotated-Strap End Column Cap from Simpson Strong-Tie, engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications in wood construction. Built for nominal 8x beams and 8x posts, this end column cap features straps rotated 90 deg. to accommodate framing layouts where a standard strap orientation would not suit the beam direction or installation geometry. The seat of the column cap provides an additional bearing surface that extends beyond the side of the column, helping distribute the load from the beam and provide critical support for the connection. Fabricated from 3-gauge steel with a Simpson Strong-Tie gray paint finish and certified welds, this connector is built for demanding structural environments including those subject to earthquake or wind loading.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - 28 screws measuring 1/4 in. x 2-1/2 in. (Model: SDS25212) are included in the package, so you have everything needed to complete the installation without sourcing additional fasteners.
• Lower-profile SDS screw fastening - The SDS screws provide a lower profile than standard through bolts and attach to a greater net section area of the column, resulting in a cleaner installation with strong, efficient load transfer.
• Certified welds - Every weld is certified for strength and loading, giving installers and engineers confidence in the structural integrity of the connection.
• Increased uplift load capacity - Uplift loads have been increased for earthquake or wind loading, making this connector well-suited for projects in high-demand seismic or wind-prone environments.
• Rotated strap configuration (90 deg.) - The ROT designation means the straps are oriented 90 deg. from the standard position, accommodating end-of-beam framing layouts that a standard column cap cannot properly serve.
• Extended bearing seat - The seat extends beyond the side of the column to distribute beam loads across a greater surface area, reducing concentrated stress at the connection point.
• Diamond holes for temporary fastening - Diamond holes allow the connector to be held in position during layout and alignment before final fastening, improving installation accuracy and saving time on the job.
• 3-gauge steel construction with gray paint finish - Heavy 3-gauge steel provides the structural mass required for large timber connections, while the Simpson Strong-Tie gray paint finish offers a durable, corrosion-resistant surface for interior and protected applications.

Why This Product

• A purpose-built solution for end-of-beam column connections in heavy timber - The ECCQ design is specifically engineered for end-of-beam applications, eliminating the need for additional brackets or braces and streamlining the connection detail in large-scale wood construction projects.
• Rotated strap geometry solves real framing challenges - Where standard column cap orientations conflict with beam direction or framing layout, the 90 deg. rotated straps provide a direct, code-compatible solution without custom fabrication or field modifications.
• Enhanced performance for high-wind and seismic conditions - With increased uplift load ratings and certified welds, this connector is engineered to handle the lateral and vertical forces imposed by earthquake or wind loading, making it a dependable choice for structurally critical connections.
• Faster installation with screws included and no bolting required - The included Strong-Drive SDS screws install faster than traditional through bolts, require no pre-drilling of bolt holes, and engage a greater net section area of the column - reducing labor time while maintaining strong load capacity.
