The Simpson BA1.81/16 Top-Flange Joist Hanger is built for engineered wood product framing and solid sawn lumber applications where reliable joist-to-header connections are essential. Designed to fit a 1-3/4 in. x 16 in. member, this top-flange hanger delivers medium load capacity with solid sawn lumber and higher load capacity when paired with engineered wood products. The BA series supports flexible nailing configurations - minimum nailing with positive-angle nailing (PAN) targets moderate load conditions, while maximum nailing accommodates higher load demands - giving framers precise control over performance without overbuilding.

Key Features

• Cost-effective one-piece design - eliminates the expense and variability of welded hangers, providing consistent strength from a single formed component
• 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
• Positive-angle nailing (PAN) support - allows minimum nailing for moderate load conditions, making installation faster while still meeting structural requirements
• Maximum nailing configuration - unlocks higher load capacity when engineered wood products are used, giving one hanger the flexibility to serve a wider range of framing scenarios
• 14-gauge steel construction - provides the structural rigidity needed for demanding residential and commercial framing applications
• G90 zinc galvanized finish - delivers extra corrosion resistance, extending service life in moisture-prone framing environments
• Available modified for sloped and/or skewed members - accommodates non-standard framing conditions, including slopes and skews up to 45 deg., so the hanger adapts to complex roof and floor framing layouts

Why This Product

• Dual-application versatility - a single hanger model supports both engineered wood products and solid sawn lumber at the same 1-3/4 in. x 16 in. member size, reducing the number of SKUs a framer needs to stock on the job site
• Rotation control without extra hardware - the full-height joist flange captures the top chord and eliminates the need for web stiffeners, cutting both material costs and installation time on every joist connection
• Scalable load performance - the choice between minimum PAN nailing and maximum nailing lets installers dial in the right load rating for the application rather than defaulting to a heavier, more expensive connector
• Corrosion-resistant finish for long-term reliability - the G90 zinc galvanized coating goes beyond standard galvanizing, making this hanger a sound choice for framing assemblies where moisture exposure is a concern
