The Simpson 8 X Rough Post Base from Simpson is an 18-gauge G90 zinc galvanized connector engineered to anchor a rough 8x nominal post to a wood supporting member. Built to deliver both uplift resistance and lateral resistance in light-duty construction, this post base is sized precisely for rough-sawn 8x lumber - making it the right fit where standard dressed lumber dimensions simply will not do. Its opposing nail pattern and compatibility with common or pneumatic nail sizes streamline installation without sacrificing structural integrity.

Key Features

• Opposing nail pattern - reduces wood splitting during installation, protecting the integrity of the post and supporting member.
• Compatible with common or pneumatic nail sizes - attains full allowable load with either nail type, giving installers flexibility without compromising rated performance.
• 18-gauge light-gauge construction - appropriately matched to light-duty applications, keeping the connector practical and cost-effective for projects that do not require heavy-gauge hardware.
• Provides both uplift and lateral resistance - addresses two critical load directions in a single connector, simplifying the structural connection at the post base.
• Sized specifically for rough 8x nominal lumber - engineered to fit rough-sawn posts rather than dressed lumber, ensuring a proper fit where rough timber is specified.
• G90 zinc galvanized coating - delivers a robust level of corrosion resistance, helping the connector hold up in a variety of construction environments over the long term.

Why This Product

• Purpose-built for rough-sawn timber - because rough 8x lumber is larger than dressed dimensional stock, a connector sized for dressed lumber will not fit correctly. This post base is designed from the ground up for rough 8x posts, so the fit is accurate and the rated load values apply as intended.
• Dual-direction load resistance in one piece - by handling both uplift and lateral forces, this connector reduces the need for supplemental hardware at the post-to-beam connection, keeping the installation clean and efficient.
• Nail-type flexibility without load penalty - the ability to reach full allowable load with either common nails or pneumatic nails means crews can use the tools and fasteners already on hand, reducing downtime and material costs on the job site.
• Made in the United States by Simpson - backed by a brand with a long-standing reputation in structural connectors, this post base is produced domestically and designed to meet the expectations of contractors and builders who specify Simpson hardware by name.

Frequently Asked Questions

What lumber size is the BC80R post base designed for?

The BC80R is designed specifically for rough 8x nominal lumber. Its dimensions - 8 inches wide, 8 inches long, and 4 inches high - are sized to accommodate rough-sawn 8x posts rather than standard dressed lumber.

What type of fasteners are required to install the BC80R?

Installation requires 0.162 x 3-1/2" nails throughout. The post flange requires six of these nails, and the base bottom requires four, for a total of ten nails. The connector attains its full allowable load using either common nail or pneumatic nail sizes of this specification.

What kind of corrosion protection does the BC80R provide?

The BC80R features a G90 zinc galvanized coating, which provides a robust level of corrosion resistance suitable for use in a variety of construction environments.

What structural functions does the BC80R post base perform?

The BC80R is designed to connect a post to a wood supporting member and provides both uplift resistance and lateral resistance. Its 18-gauge construction makes it appropriate for light-duty connection applications.
