The Simpson ECC5 1/4-6ROT End Column Cap with Rotated Straps is a heavy-duty structural connector from Simpson engineered for end-of-beam column-to-beam connections in wood construction. Designed to pair a 5-1/8 in. beam with a 6X post, this end column cap features straps rotated 90 deg. so the seat extends beyond one side of the column, providing an additional bearing surface that helps distribute load and deliver reliable structural support. Built from 3 gauge steel with Simpson Strong-Tie gray paint finish, it is a purpose-built solution for post and beam framing applications that demand strength, code compliance, and increased resistance to seismic or high-wind uplift forces.

Key Features

• Rotated Strap Configuration - Straps rotated 90 deg. extend the seat beyond one side of the column, creating an additional bearing surface that improves load distribution in end-of-beam installations.
• 3 Gauge Steel Construction - Heavy-gauge material provides the structural integrity needed for demanding post and beam framing connections, giving buyers confidence in long-term performance.
• Simpson Strong-Tie Gray Paint Finish - A consistent protective coating helps guard against corrosion in typical wood construction environments, supporting durability over the life of the structure.
• Increased Uplift Load Resistance - Enhanced uplift capacity makes this connector well-suited for seismic zones and high-wind regions where earthquake or wind loading requirements must be met.
• NDS Code-Compliant Bolt Spacing - Bolt spacing meets National Design Specification requirements, helping contractors and builders satisfy code review and inspection standards without modification.
• Certified Welds - Welds are certified for strength and load performance, providing builders with documented assurance in the connector's structural integrity.
• Precise Fit for 5-1/8 in. Beam and 6X Post - Sized specifically for this common glulam and engineered lumber pairing, eliminating guesswork and ensuring a secure, properly aligned connection at the column cap.

Why This Product

• Built for End-of-Beam Applications Where Others Fall Short - The rotated strap orientation and extended bearing seat address the unique structural demands of end column cap installations, making this connector a precise match for end-of-beam column-to-beam framing rather than a generic workaround.
• Engineered for Earthquake and High-Wind Zones - With uplift loads specifically increased for seismic and wind loading conditions, this connector helps structures meet the heightened performance requirements of projects in challenging climate and geographic environments.
• American-Made, Heavy-Gauge Steel Quality - Produced in the United States from 3 gauge steel with certified welds, this end column cap delivers consistent material quality and weld integrity that structural framing projects depend on.
• Straightforward Code Compliance - NDS code-compliant bolt spacing and certified weld documentation reduce the burden on builders during plan review and inspection, keeping projects on track without costly field modifications.

Frequently Asked Questions

What beam and post sizes is the ECC5 1/4-6ROT designed to fit?

This end column cap is specifically engineered for use with a 5-1/8" beam and a 6X post, making it suitable for structural framing applications where those two dimensions meet at an end-of-beam connection.

What does "rotated straps" mean on this column cap?

The rotated straps on the ECC5 1/4-6ROT are oriented 90 deg. relative to a standard column cap configuration. This rotation is specifically designed to accommodate end-of-beam column cap applications, where the seat extends beyond one side of the column to provide additional bearing surface area.

What fasteners are required to install this column cap?

Installation requires 3/4" machine bolts - two for the beam connection and two for the post connection. The connector also includes diamond holes to assist with temporary fastening during the installation process.

What material and finish is used on the ECC5 1/4-6ROT?

The ECC5 1/4-6ROT is constructed from 3 gauge steel, which provides superior load-bearing capacity, and it features a Simpson Strong-Tie gray paint finish. The connector also incorporates certified welds for added confidence in strength and loading performance.
