The Simpson 6.75" X 10.5" Glulam Column Base is a heavy-duty structural connector engineered to anchor glulam and engineered wood product columns securely to concrete foundations. Designed for either cast-in-place or wet-set installation, the base plate sits flush with the concrete surface to deliver full post bearing and a clean, stable connection point. Finished in Simpson Strong-Tie gray paint and produced in the United States, this column base is built to meet the demands of both residential and commercial structural applications where reliable post-to-foundation performance is essential.

Key Features

• Sized specifically for 6.75" x 10.5" glulam columns - ensures a precise, engineered fit for glulam and same-dimension engineered wood product columns, eliminating guesswork and reducing installation error.
• Cast-in-place or wet-set installation - gives contractors and builders flexibility to incorporate the base during concrete pours or set it while concrete is still wet, adapting to different jobsite workflows.
• Flush base plate design - positions the plate level with the concrete surface to provide full post bearing, promoting even load transfer from column to foundation.
• Engineered for wind uplift and seismic resistance - suitable for applications requiring enhanced structural resistance, making it appropriate for both standard builds and projects in demanding load environments.
• Simpson Strong-Tie gray paint finish - provides a consistent, finished appearance and surface protection suited to structural connector applications.
• American-made construction - produced domestically under Simpson's quality standards, offering confidence in material consistency and manufacturing oversight.

Why This Product

• Purpose-built fit for glulam construction - rather than a generic post base adapted for glulam use, this connector is sized and approved specifically for 6.75" x 10.5" glulam and engineered wood product columns, supporting structural integrity from the ground up.
• Versatile installation method - compatibility with both cast-in-place and wet-set concrete installation makes this base a practical choice across a wide range of foundation types and construction schedules.
• Dual-application suitability - approved for residential and commercial structural post-to-foundation connections, as well as applications requiring resistance to wind uplift and seismic forces, broadening its usefulness across project types.
• Backed by a recognized structural connector brand - Simpson has a well-established presence in structural connector engineering, giving builders and specifiers confidence when selecting this column base for load-bearing applications.

Frequently Asked Questions

What column size is the CB7-10.5 designed to fit?

The CB7-10.5 is specifically sized for Glulam 6.75" x 10.5" columns. It is also suitable for engineered wood product columns of the same dimensions, making it appropriate for both residential and commercial structural applications.

How is the CB7-10.5 installed in concrete?

The CB7-10.5 is designed for either cast-in-place or wet-set installation into concrete. The base plate sits flush with the concrete surface, which provides full post bearing and a stable foundation connection.

What fasteners are required to install the CB7-10.5?

Installation requires two 5/8" bolts. The bolt hole locations are designed to meet code-required spacing in order to achieve optimal load capacity.

Is the CB7-10.5 suitable for areas with wind or seismic loading requirements?

Yes. The CB7-10.5 features increased uplift resistance, making it well suited for structural applications subject to wind or seismic loading conditions.
