The Simpson Strong-Tie ECCQ7.1-7.1SDS25 is a heavy-duty end column cap engineered to deliver strong, reliable column-beam connections in end-of-beam wood construction applications. Fabricated from 3-gauge steel and finished with Simpson Strong-Tie Gray paint, this connector features an extended seat bearing surface that distributes load effectively from the beam while providing robust support at the connection point. Included Strong-Drive SDS Heavy-Duty Connector screws allow for faster installation and engage a greater net section area of the column compared to traditional bolt attachments, making the ECCQ7.1-7.1SDS25 a trusted solution for structural integrity in demanding wood frame assemblies.

Key Features

• Designed for strong column-beam connections in end-of-beam applications in wood construction
• Extended seat bearing surface distributes load from the beam beyond the side of the column for enhanced support
• Uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation
• SDS screws attach to a greater net section area of the column than standard bolt attachments
• Lower profile than standard through bolts thanks to SDS screw fastening
• Certified welds for confidence in strength and loading performance
• Increased uplift loads for earthquake or wind loading conditions
• Diamond holes allow for temporary fastening during installation
• Manufactured from 3-gauge steel for superior strength and durability
• Finished with Simpson Strong-Tie Gray paint for corrosion resistance

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.
