The Simpson ECCQ74SDS2.5ROT 6-3/4 in. Beam 4x Post End Column Cap is a heavy-duty structural connector engineered for reliable end-of-beam column-to-beam connections in wood construction. Built by Simpson from 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this end column cap features rotated straps and comes pre-loaded with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, making it a ready-to-install solution for post and beam framing applications that demand high uplift resistance and structural integrity.

Key Features

• 3-gauge steel construction - provides heavy-duty strength for demanding structural post and beam connections in both residential and commercial wood framing projects
• Rotated strap orientation (90 deg.) - allows for flexible installation where standard strap positioning is not compatible, ensuring the connector fits your specific framing layout
• Extended bearing seat design - distributes load from the beam efficiently to the post, supporting high uplift capacity for applications subject to earthquake or wind loading
• Pre-installed 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws included - eliminates the need to source separate fasteners, so installation can begin immediately on the job site
• Simpson Strong-Tie Gray paint finish - delivers lasting corrosion resistance suited to the exposure conditions common in structural framing applications
• Designed specifically for 6-3/4 in. wide beams and 4x posts - ensures a precise, engineered fit that eliminates guesswork and supports code-compliant column cap installations
• Diamond holes included for temporary fastening - allow for accurate positioning and adjustment during installation before final fastening, reducing the chance of costly errors

Why This Product

• Built for high-demand structural applications - the 3-gauge steel body and SDS screw fastening system combine to deliver high uplift load capacity, making this connector well-suited for seismic and high-wind construction zones where connection performance is critical
• Rotated strap configuration solves real framing challenges - the 90 deg. rotated straps address orientation constraints that standard column caps cannot accommodate, giving builders a code-compatible solution without custom fabrication
• Everything needed for installation ships with the connector - with both beam-side and post-side SDS screws included, this end column cap arrives as a complete assembly package, saving time and reducing the risk of mismatched fasteners on the job
• Made in the United States by Simpson - this connector is produced domestically under the quality standards Simpson is recognized for, giving structural professionals confidence in consistency and traceability for permitted projects

Frequently Asked Questions

What beam width and post size is the ECCQ74SDS2.5ROT designed to fit?

This column cap is designed for use with a 6-3/4 in. wide beam and a 4x post. The connector dimensions include a W1 of 6-7/8 in., a W2 of 3-5/8 in., a length of 8-1/2 in., and a height of 7 in.

What fasteners come included, and why are they preferred over standard bolts?

The ECCQ74SDS2.5ROT comes pre-installed with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws. These screws offer a lower profile than standard through bolts and attach to a greater net section area of the column compared to standard bolt attachment, providing a stronger and cleaner connection.

What is the purpose of the rotated strap configuration on this column cap?

The rotated strap configuration gives this model its "ROT" designation and allows for a flexible installation orientation compared to the standard strap layout. This makes it particularly useful in end-of-beam applications where the standard orientation may not be practical.

What material and finish is used, and is this product suitable for demanding structural applications?

The ECCQ74SDS2.5ROT is manufactured from 3-gauge steel with a Simpson Strong-Tie Gray paint finish. It features certified welds, an extended bearing seat design for superior load distribution, and is rated for earthquake and wind loading conditions, making it well suited for demanding structural connections in both residential and commercial wood framing projects.
