The Simpson ECCQ7.1-7.1SDS25 7x Beam 7x Post End Column Cap with SDS Screws is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections in wood frame construction. Built by Simpson to handle demanding structural loads, this end column cap is designed to deliver reliable performance in applications where increased uplift resistance is critical - including projects subject to earthquake and wind loading requirements.

Key Features

• Designed for 7x beam and 7x post connections - purpose-sized fitment means a secure, accurate installation without field modification or guesswork.
• Fabricated from 3-gauge steel - heavy-gauge construction provides the structural strength needed for load-bearing column-to-beam connections in demanding wood assemblies.
• Finished with Simpson Strong-Tie Gray Paint - provides a corrosion-resistant surface coating that helps protect the connector over the life of the structure.
• Includes Strong-Drive SDS Heavy-Duty Connector Screws for both beam and post - all required fasteners ship with the cap, allowing installation to begin immediately without sourcing additional hardware separately.
• SDS screw attachment engages a greater net section area of the column than traditional bolt connections - this translates to stronger, more efficient load transfer at the connection point.
• Diamond holes available for temporary fastening - assists with positioning during installation, making it easier to hold the cap in place before final fastening.
• Approved for wind and seismic uplift applications - the connector meets requirements for structural connections demanding certified uplift resistance, giving builders and inspectors added confidence on code-sensitive projects.

Why This Product

• Complete out-of-the-box solution - the column cap ships with all SDS screws for both the beam and post connections included, so there are no additional fastener purchases needed to complete the installation.
• Built for high-demand structural environments - approved for use in end-of-beam wood construction applications where resistance to earthquake and wind uplift forces is a project requirement, making it a sound choice for structurally engineered builds.
• Made in the United States by Simpson - domestic production under a trusted structural connector brand supports consistent quality standards and traceability for commercial and residential construction projects alike.
• Installer-friendly design - diamond holes for temporary fastening combined with included SDS screws streamline the installation process, reducing time spent at the connection point without sacrificing structural performance.

Frequently Asked Questions

What size beam and post is the ECCQ7.1-7.1SDS25 designed to fit?

The ECCQ7.1-7.1SDS25 is designed for use with a 7x beam and a 7x post, as indicated by the 7.1-7.1 designation in the model number.

What type of fasteners are included, and why are they preferred over traditional bolts?

The connector includes Strong-Drive SDS Heavy-Duty Connector screws. These screws allow for faster installation, attach to a greater net section area of the column than standard bolt attachments, and result in a lower profile at the connection point compared to standard through bolts.

What material and finish is used on the ECCQ7.1-7.1SDS25?

The ECCQ7.1-7.1SDS25 is fabricated from 3-gauge steel and finished with Simpson Strong-Tie Gray paint for corrosion resistance.

Is the ECCQ7.1-7.1SDS25 suitable for use in areas subject to earthquake or wind loading?

Yes, the ECCQ7.1-7.1SDS25 features increased uplift load capacity, making it suitable for construction applications where earthquake or wind loading conditions must be accounted for.
