The Simpson HU312-2 Heavy-Duty Face-Mount Joist Hanger is a professional-grade structural connector engineered by Simpson Strong-Tie to support double 3x12 lumber members in demanding framing applications. Built for projects where additional strength and safety factors are required, this heavy-duty hanger is the go-to choice of engineers and contractors for both residential construction and code-compliant structural builds.

Key Features

• "U" design allows for flexibility of placement on the header - makes positioning easier during installation, reducing layout time and giving you more control on the job site
• Nominal joist size: Double 3x12 - purpose-built to seat double 3x12 members securely, ensuring a proper fit for heavy structural framing without guesswork
• Made from 14-gauge steel - provides the structural rigidity and load-bearing capacity needed for heavy-duty face-mount hanger applications
• Galvanized (G90) for extra corrosion resistance - the zinc galvanized finish helps protect against corrosion, supporting long-term durability across a range of construction environments
