The Simpson FJA Foundation Joist Anchor is engineered to create a direct, reliable connection between a foundation and a floor joist, resisting both uplift and lateral forces in demanding structural applications. Built from 12-gauge steel with a G90 galvanized finish, this foundation anchor installs by nailing or bolting directly into floor joists, streamlining the process for contractors and builders working on new construction or retrofit projects. Measuring 19-1/2 in. x 2-1/2 in., the FJA is a simple and versatile anchor suited for light- and heavy-duty uses wherever a secure joist-to-foundation connection is required.

Key Features

• Direct joist-to-foundation connection - provides a structural link that effectively resists uplift and lateral forces, keeping floor systems securely anchored under load.
• Adjustable bend line, one time only, up to 20 deg. - lets installers fine-tune the anchor's angle to match real-world conditions, reducing the need for additional hardware or custom fabrication.
• Rated for increased loads under wind or seismic forces - gives builders confidence that the connection meets the demands of high-wind zones and earthquake-prone regions.
• Made from 12-gauge steel - delivers the structural strength needed for both light-duty residential framing and heavy-duty commercial or retrofit applications.
• G90 galvanized coating - provides enhanced corrosion resistance, extending the service life of the anchor in moisture-prone environments near concrete foundations.

Why This Product

• One anchor, two applications - the FJA works equally well in new construction and retrofit projects, eliminating the need to source different hardware depending on the job type.
• Field-adjustable design - the ability to bend the anchor up to 20 deg. along its bend line means installers can adapt to minor alignment variations on site without compromising the structural connection.
• Built for code-sensitive environments - with increased load ratings for wind and seismic forces, the FJA is a dependable choice for projects in regions with strict structural requirements.
• Corrosion-resistant construction from a trusted brand - Simpson's G90 galvanized, 12-gauge steel construction ensures the anchor holds up in the damp, concrete-adjacent conditions typical of foundation connections.
