The Simpson ECCQ64SDS2.5ROT 6x Beam 4x Post End Column Cap with Rotated Straps and SDS2.5 Screws is an engineered connector built for high-strength end-of-beam column-to-beam connections in wood construction. Fabricated from 7-gauge steel and finished with Simpson Strong-Tie Gray paint, this end column cap arrives with rotated straps oriented 90 deg. from the standard position and includes all Strong-Drive SDS Heavy-Duty Connector screws needed for a complete installation. Certified welds and enhanced uplift load ratings make it a dependable choice for post-and-beam structures in seismic zones and high-wind load environments.

Key Features

• Rotated strap orientation (90 deg.) - positions fastening straps to suit end-of-beam layouts where standard strap alignment would interfere with framing members, giving installers a clean fit without field modification.
• 7-gauge steel construction - delivers the structural rigidity and load-carrying capacity needed for heavy timber and post-and-beam applications, supporting confidence in demanding structural environments.
• Includes Strong-Drive SDS Heavy-Duty Connector screws for both beam and post - everything required for fastening arrives with the connector, eliminating a separate hardware order and keeping the installation moving.
• SDS screw attachment engages a greater net section area than standard bolt attachment - this improves connection strength while maintaining a low profile, reducing the visual bulk of the finished connection.
• Diamond holes for temporary fastening - assist with alignment during installation, allowing the connector to be held in position before final fastening and reducing the chance of costly placement errors.
• Simpson Strong-Tie Gray paint finish - provides a consistent, professional appearance and baseline corrosion resistance suited to the interior and protected structural environments typical of post-and-beam construction.
• Certified welds with enhanced uplift load ratings - qualify this connector for structural connections requiring resistance to seismic (earthquake) loading and high-wind forces, supporting code-confidence in regulated building projects.

Why This Product

• Purpose-built for end-of-beam applications - unlike standard column caps, this connector is specifically configured for end-of-beam column-to-beam connections, meaning the geometry, strap orientation, and fastener pattern all work together without requiring field adaptation.
• A complete, hardware-included connector - the inclusion of Strong-Drive SDS Heavy-Duty Connector screws for both the beam and post side means no guesswork on fastener spec and no return trips for hardware, keeping structural projects on schedule.
• Engineered for high-demand structural environments - certified welds, heavy-gauge steel, and enhanced uplift load ratings make this end column cap a traceable, specification-ready choice for projects in seismic zones or high-wind regions where connection performance must be documented.
• Low-profile fastening over traditional through-bolt methods - SDS screw attachment reduces visual bulk at the connection point while engaging a greater net section area of the post, offering both a cleaner aesthetic and improved structural performance in heavy timber construction.

Frequently Asked Questions

What beam and post sizes is this column cap designed to fit?

The ECCQ64SDS2.5ROT is designed for use with a 6x beam and a 4x post. The beam width accommodated is 5-1/4 in. or 5-1/2 in., with dimension W1 at 5-1/2 in.

What does "rotated straps" mean and why does it matter for installation?

The rotated straps on this column cap are oriented at 90 deg. relative to a standard configuration. This rotation provides flexible installation options, making the connector better suited for specific framing layouts where a standard strap orientation would not work as effectively.

Are fasteners included, and what type are they?

Yes, this column cap ships complete with 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, contributing to a stronger and cleaner connection.

Is this connector appropriate for use in seismic or high-wind construction zones?

Yes, the ECCQ64SDS2.5ROT features increased uplift load ratings specifically suited for earthquake and high-wind loading conditions. Combined with certified welds and an extended seat bearing surface for efficient load distribution, it is engineered for demanding structural environments where code-compliant performance is required.
