The Simpson ECCQ5-6SDS2.5 End Column Cap is a heavy-duty structural connector engineered by Simpson to deliver a high-capacity connection for column-beam combinations in end-of-beam wood construction applications. Built from 3-gauge steel and finished in Simpson Strong-Tie gray paint, this end column cap is sized for a 5-1/8 in. beam and a 6x post, making it a reliable choice for residential and commercial structural framing where strong, code-compliant load transfer between column and beam members is required. The connector ships complete with 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws, so your installation can start immediately without sourcing additional fasteners.

Key Features

• Strong-Drive SDS screw installation - eliminates the need to drill through-bolt holes, speeding up installation and preserving a greater net section area of the column for a stronger overall connection.
• Lower-profile fastener design - SDS screws sit closer to the surface than standard through bolts, resulting in a cleaner, less obtrusive appearance where the column and beam meet.
• 3-gauge steel construction - the heavy-gauge material delivers the structural rigidity and load capacity expected in demanding residential and commercial framing applications.
• Simpson Strong-Tie gray paint finish - provides a consistent, finished look and helps protect the connector during handling and installation.
• SDS screws included in the box - the required 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws come packaged with the connector, reducing trips to the hardware store and keeping your project on schedule.

Why This Product

• Engineered for high-capacity structural connections - this end column cap is specifically designed to handle the load transfer demands of column-to-beam joints in end-of-beam wood construction, making it appropriate for projects where connector strength and building code compliance are non-negotiable.
• Faster installation without sacrificing strength - because Strong-Drive SDS screws replace traditional through bolts, installers avoid time-consuming drilling steps while the column retains more of its net section area, supporting a stronger finished connection.
• Everything needed arrives in one package - with the required SDS screws included, this connector is a complete, ready-to-install solution that simplifies procurement for contractors and builders alike.
• Trusted Simpson engineering and manufacturing standards - engineered and tested to perform, Simpson connectors are a go-to choice for engineers and contractors working on projects that must meet structural performance and building code requirements.
