Product Description
The Simpson BA4.75/11.88 BA Top-Flange Joist Hanger is engineered for reliable performance in both engineered wood and solid sawn lumber applications. Designed to accommodate a double 2-5/16 in. x 11-7/8 in. member, this top-flange hanger delivers medium load capacity with solid sawn lumber and elevated load capacity with engineered wood products. The BA series supports flexible nailing options - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, and maximum nailing for higher load demands - making it a versatile choice for a wide range of structural framing projects.
