The Simpson End Column Cap for 8X Beam and 4X Post with Rotated Straps is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections in wood construction. Built by Simpson from 3-gauge steel and finished with Simpson Strong-Tie gray paint, this end column cap features straps rotated 90 deg. to accommodate layout configurations where standard strap orientation would not work. The extended seat provides additional bearing surface beyond one side of the column, helping distribute load from the beam and supporting reliable, code-compliant performance in demanding structural applications including seismic and high-wind zones.

Key Features

• 3-gauge steel construction - delivers the structural mass and rigidity required for heavy timber end-of-beam connections, giving engineers and builders confidence in long-term load performance.
• Rotated straps (90 deg.) - allows the connector to fit layouts where standard strap orientation is not possible, expanding its usefulness across a wider range of structural configurations.
• Extended seat bearing surface - projects beyond one side of the column to increase the contact area between beam and cap, helping distribute load more effectively at the connection point.
• Certified welds - provide verified joint integrity so structural professionals can rely on rated uplift and load values with confidence.
• Engineered for increased uplift load capacity - makes this end column cap suitable for seismic zones and high-wind applications where connections must resist significant upward forces.
• NDS code-compliant bolt spacing - simplifies the permitting and inspection process by meeting recognized national design standards right out of the box.
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and a baseline level of surface protection suited to typical covered structural environments.

Why This Product

• Purpose-built for end-of-beam heavy timber work - specifically sized for an 8X beam and 4X post, this cap addresses a precise connection need that general-purpose hardware cannot reliably fulfill, reducing guesswork for structural professionals.
• Rotated strap design solves real layout problems - when framing geometry prevents standard connector orientation, the 90 deg. rotated straps allow the same proven connection strength to be achieved without compromising the structural plan.
• Rated for seismic and high-wind uplift demands - the connector is approved for applications requiring increased uplift load capacity, making it a dependable choice in regions where wind and seismic forces govern structural design.
• American-made quality from a trusted structural brand - produced by Simpson with certified welds and a finish applied to a strict standard, this end column cap reflects the manufacturing consistency that design professionals and inspectors expect on the job site.

Frequently Asked Questions

What beam and post sizes is the ECC84ROT designed for?

The ECC84ROT is specifically designed for use with an 8X beam and a 4X post, making it suitable for heavy timber end-of-beam connection applications.

What fasteners are required for installation?

Installation requires 3/4" machine bolts - two for the beam connection and two for the post connection. Fasteners are not included and must be sourced separately.

What does the rotated strap configuration mean?

The "ROT" designation indicates that the straps on this column cap have been rotated 90 deg. from the standard orientation. This configuration is used to accommodate specific structural layouts. Note that the W2 dimension on straps rotated 90 deg. is limited by the W1 dimension.

Is the ECC84ROT suitable for high-wind or seismic applications?

Yes. The ECC84ROT features
