The Simpson BA4.75/16 Top-Flange Joist Hanger is a heavy-duty structural connector designed for double 2-5/16 in. x 16 in. engineered wood and solid sawn lumber framing applications. Built from 12-gauge steel with a G90 zinc galvanized finish, this top-flange hanger delivers medium load capacity with solid sawn lumber and higher load capacity when paired with engineered wood products. The BA design supports both minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing configurations for demanding structural requirements - making it a reliable, code-conscious solution for joist-to-beam and joist-to-header connections across a wide range of framing projects.

Key Features

• Cost-effective one-piece design - eliminates the added expense and complexity of welded hangers, simplifying installation without sacrificing structural performance
• Full-height joist flange - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, reducing material costs and installation steps
• Dual nailing configurations (minimum PAN and maximum nailing) - gives installers flexibility to target moderate or higher load conditions with a single hanger model, adapting to varying project demands
• 12-gauge steel construction - provides the thickness and strength needed for medium to higher load structural framing connections in engineered wood product and solid sawn lumber applications
• G90 zinc galvanized finish - delivers extra corrosion resistance for long-term durability in demanding construction environments
• Available for sloped and/or skewed member configurations via special order - extends the hanger's usefulness beyond standard installations to accommodate non-perpendicular framing conditions

Why This Product

• One connector, broader load range - the BA series supports both moderate and higher load conditions by allowing minimum or maximum nailing, so one hanger model can serve multiple structural scenarios without requiring a separate product for each application
• Engineered to work with today's framing materials - explicitly approved for engineered wood products as well as solid sawn lumber, this hanger accommodates the double-member joist sizes commonly used in modern floor and roof framing systems
• Rotation control built in - the full-height joist flange actively captures the top chord to prevent joist rotation, a structural safeguard that also removes the need for web stiffeners and keeps your material list and labor time lean
• Trusted Simpson quality with domestic manufacturing - produced in the United States from 12-gauge steel with a G90 galvanized coating, this hanger reflects Simpson's commitment to consistent material standards and corrosion protection in structural connectors
