The Simpson ECC7 1/8-8 End Column Cap is a heavy-duty structural connector from Simpson engineered for end-of-beam column-to-beam connections in wood frame and heavy timber construction. Designed to pair a 7" beam with an 8X post, this end column cap features a seat that provides an extended bearing surface beyond one side of the column, helping to distribute load from the beam to the post with confidence. Built from 3-gauge steel with a Simpson gray paint finish and secured with 3/4" machine bolts, this connector is built for structural applications where load integrity is critical - including connections subject to earthquake or wind uplift forces.

Key Features

• 3-gauge steel construction - provides the structural mass and rigidity required for demanding column-to-beam load transfer in heavy timber and post-and-beam applications
• Extended bearing seat design - projects beyond one side of the column to increase the load-bearing surface area, improving load distribution from beam to post at end-of-beam locations
• Certified welds - deliver verified strength and reliable load performance, giving builders and engineers confidence in the connection under real working conditions
• Engineered for elevated uplift loads - specifically designed to handle the increased demands of earthquake and wind loading conditions, making this cap suitable for high-load structural environments
• Bolt spacing meeting NDS code requirements - ensures the fastener layout satisfies code expectations for structural wood connections, simplifying inspection and approval
• Simpson gray paint finish - provides a consistent, clean appearance while offering a baseline level of protection suited to the applications this connector is approved for
• Designed for 7" beams and 8X posts - purpose-built dimensions eliminate guesswork and ensure a precise, secure fit in the intended connection without modification

Why This Product

• Purpose-matched sizing for a specific structural pairing - with dimensions optimized for a 7" beam and 8X post, this end column cap fits the intended connection precisely, reducing installation complications and supporting a clean, code-compliant assembly
• Trusted Simpson engineering for critical load paths - coming from Simpson, a brand recognized in structural connector manufacturing, this cap is designed to perform in end-of-beam applications where load distribution and connection integrity directly affect structural safety
• Dual-load capability for wind and seismic zones - the increased uplift load capacity built into this connector makes it a practical choice for projects in regions where earthquake or high-wind conditions are a design consideration, without requiring a specialty upgrade
• Domestically produced for consistent quality - manufactured in the United States, this end column cap is produced under consistent quality standards, supporting confidence in material and fabrication reliability for structural use

Frequently Asked Questions

What beam and post sizes does the ECC7 1/8-8 accommodate?

The ECC7 1/8-8 is specifically designed for use with a 7" beam and an 8X post in end-of-beam column cap applications.

What fasteners are required to install this column cap?

Installation requires four 3/4" machine bolts in total - two for the beam connection and two for the post connection. Fasteners are not included with the column cap.

Does the ECC7 1/8-8 meet NDS code requirements?

Yes. The bolt spacing on the ECC End Column Cap is designed to meet NDS (National Design Specification) code requirements to ensure optimal structural performance.

Is the ECC7 1/8-8 suitable for high-wind or seismic applications?

Yes. The ECC7 1/8-8 features increased uplift load values specifically designed to address the demands of earthquake or wind loading conditions.
