The Simpson BA Top-Flange Joist Hanger for 3-1/2 in. x 16 in. Engineered Wood from Simpson is a heavy-duty, single-piece connector built for both engineered wood products and solid sawn lumber framing applications. Engineered to carry medium loads with solid sawn lumber and higher loads with engineered wood, this top-flange hanger offers flexible nailing options - minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for heavier structural demands - making it a dependable choice for a wide range of residential and commercial framing projects.

Key Features

• Cost-effective one-piece design - eliminates the expense and complexity of welded hangers, reducing material and labor costs on the job site
• Full-height joist flange that captures the top chord of the joist - prevents rotation and eliminates the need for web stiffeners, simplifying installation and saving time
• Dual nailing options including positive-angle nailing (PAN) - allows the installer to match nailing patterns to actual load requirements, providing versatility across varying structural conditions
• 14-gauge steel construction - delivers the structural strength and rigidity required for medium-to-high load beam and joist hanger applications
• Zinc Galvanized G90 finish - provides a corrosion-resistant coating suitable for protected interior framing environments where moisture resistance is a factor
• Available for sloped and/or skewed configurations - accommodates non-standard framing angles, giving builders flexibility on complex structural layouts without sourcing a different product

Why This Product

• Engineered for both lumber types - because the BA hanger is rated for both engineered wood products and solid sawn lumber, contractors and builders can use a single connector solution across mixed-material framing projects rather than stocking multiple hanger types
• Eliminates web stiffeners by design - the full-height joist flange captures and stabilizes the top chord of the joist directly, removing an extra installation step and reducing the hardware needed to complete the connection
• One-piece stamped construction over welded alternatives - the integrated design means fewer components to source, fewer potential failure points, and a more straightforward installation process compared to multi-piece or welded beam hangers
• Scalable load capacity through nailing flexibility - the ability to switch between minimum PAN nailing and maximum nailing patterns lets the same hanger serve moderate or higher structural load requirements, reducing the need to specify a different product as load demands change
