The Simpson 4x4 Face-Mount Joist Hanger U44 is a precision-formed, galvanized steel connector engineered by Simpson for reliable joist-to-header connections in wood-framed construction. Its face-mount design simplifies installation while delivering consistent structural support for 4x4 lumber across a wide range of framing applications, from solid sawn dimensional lumber to engineered wood products.

Key Features

• Face-mount configuration - attaches directly to the face of the header, making alignment and installation straightforward for framers working in standard wood-framed construction
• 16-gauge steel construction - provides consistent dimensional accuracy and structural integrity so the hanger seats properly and performs reliably under load
• G90 zinc galvanized coating - delivers a protective barrier against corrosion and oxidation, helping extend service life in typical framing environments
• Sized specifically for 4x4 lumber - the interior seat width and overall width are matched to cradle a standard 4x4 joist or beam securely, reducing the risk of improper fit
• Compatible with multiple lumber types - approved for solid sawn lumber, rough lumber, I-joists, glulam, and structural composite lumber, giving builders flexibility across different framing assemblies
• Domestically produced - manufactured in the United States to consistent quality standards

Why This Product

• Purpose-built fit for 4x4 framing - designed specifically for 4x4 joist-to-header connections, this hanger eliminates guesswork about sizing and compatibility, making it a direct solution for standard dimensional lumber framing as well as engineered wood applications
• Corrosion protection where it counts - the G90 zinc galvanized coating guards against oxidation in the environments where joist hangers are commonly exposed, supporting long-term performance without additional treatment
• Versatile across lumber species and grades - approved for Douglas Fir, Southern Pine, SPF, Hem-Fir, rough lumber, I-joists, glulam, and SCL, so a single hanger model covers a broad range of framing scenarios without requiring multiple product SKUs
• Trusted brand with consistent quality - engineered and produced by Simpson, a name widely recognized in structural connectors, with domestic manufacturing ensuring dimensional consistency from hanger to hanger

Frequently Asked Questions

What size lumber is the U44 designed to support?

The U44 is designed for use with 4x4 lumber. Its interior seat width of 2 in. and width of 3-9/16 in. are sized to properly cradle a standard 4x4 joist or beam in a joist-to-header application.

What type of coating does the U44 have, and why does it matter?

The U44 features a G90 zinc galvanized coating, which provides a protective layer against corrosion and oxidation. This coating helps extend the service life of the hanger in typical wood-framed construction environments.

Can the U44 be used with engineered wood products like I-joists or glulam beams?

Yes. The U44 is compatible with a variety of wood products including solid sawn lumber, rough lumber, I-joists, glulam, and structural composite lumber (SCL). Refer to the appropriate load tables linked in the Load Tables / Values / Installation section above for specific allowable load values for each application.

Is the U44 available in custom configurations?

Yes, configurable options are available. Use the Contact Us link in the Options section above and refer to the U/HU Hangers technical bulletin for guidance on ordering a custom U hanger configuration to meet specific project requirements.
