The Simpson End Column Cap for 10x Beam and 6x Post with Rotated Straps and SDS Screws is a heavy-duty structural connector engineered for end-of-beam column-to-beam connections in demanding wood construction projects. Built by Simpson for applications requiring verified load capacity and resistance to uplift forces from seismic and high-wind conditions, this rotated-strap end cap delivers a precise, secure fit where a standard strap orientation is not suitable. The included 1/4 in. x 2 1/2 in. Strong-Drive SDS Heavy-Duty Connector screws allow for a high-strength installation without the complexity of traditional through bolts, keeping the connection clean and structurally sound at end-of-beam post locations.

Key Features

• Rotated strap configuration - purpose-built for end-of-beam placement where a conventional strap orientation would not provide a proper structural fit, giving builders a reliable solution at challenging connection points.
• Sized for 10x beam and 6x post pairing - engineered to specific lumber dimensions, ensuring a precise structural fit that eliminates guesswork and reduces installation errors on the job site.
• Includes 28 Strong-Drive SDS Heavy-Duty Connector screws (14 for beam, 14 for post) - all fasteners are provided in the box, allowing installers to complete the connection without sourcing separate hardware.
• 3-gauge steel construction - the heavy material gauge delivers the structural strength needed for high-uplift and lateral-load applications, including earthquake and wind-resistant framing.
• Simpson Strong-Tie gray paint finish - provides a durable protective coating suited to structural interior and covered exterior applications, maintaining the integrity of the connector over time.
• Certified weld strength and load verification - documented performance data supports code-compliant design and gives engineers and inspectors the confidence to approve the connection without additional testing.
• Lower-profile fastener system - SDS screws eliminate the need for through bolts, reducing beam splitting risk and allowing faster installation in tight or confined framing conditions.

Why This Product

• Purpose-matched for a specific structural pairing - designed exclusively for 10x beam and 6x post connections, this connector removes ambiguity from the selection process and ensures the hardware matches the load path exactly as engineered.
• Complete fastener package included - with 14 SDS screws for the beam and 14 for the post already included, the connection is fully equipped out of the box, reducing trips to the hardware supplier and keeping the project on schedule.
• Built for high-demand load conditions - approved for applications requiring high uplift resistance under earthquake or wind loading, this column cap is a dependable choice for structural framing in regions with strict building code requirements.
• American-made quality from Simpson - produced in the United States, this connector comes from a brand with a long-standing reputation in structural wood connections, backed by certified load data that supports engineering review and inspection approval.

Frequently Asked Questions

What beam and post sizes is this column cap designed for?

The ECCQ106SDS2.5ROT is specifically engineered for use with a 10x beam and a 6x post, making it important to verify your lumber dimensions before installation to ensure a proper structural fit.

What does the "ROT" designation mean for this product?

The "ROT" designation indicates a rotated strap configuration, which is the defining feature of this ECCQ ROT variant. This rotated strap design is intended for versatile end-of-beam placement, allowing the connector to be used effectively at end-of-beam locations where a standard strap orientation would not be suitable.

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

This column cap includes Strong-Drive SDS Heavy-Duty Connector screws. These screws are preferred over traditional through bolts because they provide a lower profile installation, attach to a greater net section area of the column than bolt attachment typically allows, and enable faster high-strength installation without the bulk associated with standard through bolts.

What material and finish is the ECCQ106SDS2.5ROT made from?

The ECCQ106SDS2.5ROT is fabricated from 3-gauge steel and features a Simpson Strong-Tie gray paint finish, providing durability for structural wood construction applications.
