The Simpson U3512-2 U Galvanized Face-Mount Joist Hanger from Simpson is a heavy-duty structural connector designed for reliable joist-to-header connections in wood-framed construction. Built for double engineered wood members, this face-mount hanger accommodates an actual joist size of 4-5/8 in. x 11-1/4 in. to 11-7/8 in., making it a precise fit for engineered lumber applications where accuracy and load-carrying dependability are non-negotiable. Engineered and tested to meet the quality standards that contractors and engineers trust, it brings together durable materials, a corrosion-resistant finish, and a design that speeds up installation without sacrificing structural integrity.

Key Features

• Speed prongs locate the hanger on the header - eliminates guesswork during positioning, saving time and reducing the chance of misalignment on the job site
• Flexible face-mounted joist-to-header installation - accommodates a range of field conditions, giving installers more versatility when securing joists to headers
• Supports actual joist sizes from 4-5/8 in. x 11-1/4 in. to 11-7/8 in. - sized specifically for double engineered wood members, so the fit is secure and load transfer is consistent
• Formed from 16-gauge steel - provides the structural rigidity needed for demanding framing applications in residential and commercial construction
• G90 zinc galvanized coating - delivers extra corrosion resistance that extends the service life of the connector, even in moisture-prone environments

Why This Product

• Engineered for engineered wood - the U3512-2 is purpose-built for double engineered lumber members, giving builders a connector that matches the precision these materials require rather than relying on a generic fit
• Faster positioning, fewer mistakes - the integrated speed prongs anchor the hanger to the header before fastening begins, so installation stays accurate and efficient even under demanding job site conditions
• Built-in corrosion protection - the G90 zinc galvanized finish goes beyond basic coating, offering extra resistance to moisture and oxidation that helps the connection maintain its strength over the long term
• Trusted construction-grade quality - Simpson connectors are engineered, tested, and manufactured to meet the standards that professional contractors and structural engineers specify, making this hanger a dependable choice for code-compliant framing projects
