The Simpson BA4.75/14 Top-Flange Joist Hanger is built for double 2-5/16 in. x 14 in. engineered wood and solid sawn lumber framing connections. Designed as part of Simpson's BA series, this top-flange hanger carries medium loads with solid sawn lumber and higher loads with engineered wood products such as LVL, LSL, and PSL. Its flexible nailing system supports minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for demanding structural applications, making it a practical choice for a wide range of residential and commercial framing projects.

Key Features

• Cost-effective one-piece design - eliminates the added expense and complexity of welded hangers, reducing both material and installation costs on the job site
• Full-height joist flange - captures the top chord of the joist to prevent rotation and removes the need for web stiffeners, simplifying installation and improving structural integrity
• Flexible nailing options (PAN and maximum nailing) - allows contractors to dial in the right load capacity for the application without switching to a different hanger model
• 12-gauge steel construction - provides the thickness and rigidity needed for medium to higher load structural framing conditions
• G90 galvanized finish - delivers enhanced corrosion resistance suitable for demanding framing environments where long-term durability matters
• Available for modification to accommodate sloped and/or skewed members - gives structural framers the flexibility to address non-standard connections without sourcing a completely different product

Why This Product

• One hanger, two material types - the BA4.75/14 is engineered to perform with both engineered wood products and solid sawn lumber, so framers working with mixed materials do not need separate hanger specifications for each member type
• Built-in rotation control without extra hardware - the full-height joist flange holds the top chord firmly in place and eliminates the need for web stiffeners, cutting down on additional components and labor during installation
• Load flexibility through nailing configuration - by supporting both PAN minimum nailing and maximum nailing patterns, this hanger adapts to moderate and higher structural load conditions within the same product, reducing the need for multiple SKUs on a job
• Corrosion-resistant 12-gauge steel for long-term performance - the combination of heavy-gauge steel and a G90 galvanized coating means this hanger is built to hold up in framing applications where structural reliability over time is a priority

Frequently Asked Questions

What size joist is the BA4.75/14 designed to fit?

The BA4.75/14 is designed for a double 2-5/16 in. x 14 in. member. It is compatible with both engineered wood products (such as LVL, LSL, and PSL) and solid sawn lumber of that size.

What nails are required to install this hanger?

Install the BA4.75/14 using 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 1-1/2 in. nails in the joist. The hanger supports both minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for higher structural loads.

Does this hanger require web stiffeners?

No. The BA4.75/14 features a full-height joist flange that captures the top chord of the joist to prevent rotation, which eliminates the need for web stiffeners.

Can the BA4.75/14 be used for sloped or skewed framing applications?

The standard BA4.75/14 is designed for square framing connections, but it is available for special order to accommodate sloped and/or skewed members. Contact the manufacturer for details on custom configurations.
