The Simpson HU5.125/12 Heavy-Duty Face-Mount Joist Hanger is a structural connector engineered by Simpson for framing applications that demand additional strength and safety. Built to support double 2-1/2 in. x 11-7/8 in. I-joists and 5-1/8 in. glulam engineered wood members, this heavy-gauge face-mount hanger delivers the precise, reliable performance that engineers and contractors depend on for code-compliant residential and commercial construction. Simpson connectors are manufactured to the highest quality standards and tested to perform, making them a trusted choice wherever structural integrity is non-negotiable.

Key Features

• "U" design for flexible header placement - allows installers to position the hanger where it works best during framing, reducing layout constraints and saving time on the job site
• Compatible with double 2-1/2 in. x 11-7/8 in. I-joists and 5-1/8 in. glulam members - purpose-built for engineered wood products commonly used in modern structural framing, so the fit is precise and the connection is secure
• 14-gauge steel construction - heavy-duty material thickness provides the load capacity and structural reliability required in applications where additional strength factors are specified
• G90 zinc galvanized coating - delivers extra corrosion resistance to help the hanger hold up in moisture-prone environments, extending the service life of the connection

Why This Product

• Engineered and tested for demanding structural applications - Simpson designs this hanger specifically for structures requiring additional strength and safety factors, giving builders and engineers confidence in every connection
• Broad compatibility with engineered lumber - supporting both double I-joist and glulam configurations, this hanger works across a range of engineered wood framing systems without requiring separate hardware for each member type
• Corrosion-resistant finish suited for challenging environments - the G90 galvanized coating goes beyond a basic protective finish, making this hanger a practical choice for projects where moisture exposure is a real concern
