The Simpson Double 2x4 Face-Mount Joist Hanger U24-2 by Simpson is a precision-formed, 16-gauge galvanized connector engineered to carry double 2x4 lumber members in wood-framed construction. Its face-mount design lets the supported joist drop directly into the hanger seat against a header or carrying member, making it a reliable choice for residential and light commercial framing where a secure, code-compatible joist-to-header connection is required.

Key Features

• Face-mount installation - attaches directly to the face of a header or carrying member, allowing the joist to be seated quickly and accurately without the need for complex hardware placement
• Sized for double 2x4 lumber members - the 3-1/8 in. interior width accommodates two 2x4 boards side by side, providing a snug, consistent fit that reduces on-site adjustment
• Formed from 16-gauge steel - delivers structural rigidity and dimensional consistency, so every hanger performs the same way from the first installation to the last
• Zinc Galvanized G90 coating - provides a protective barrier against corrosion in typical construction environments, helping the connector maintain its integrity over the life of the structure
• Compatible with multiple lumber species and load table documentation - supports solid sawn lumber, rough lumber, I-joists, glulam, and structural composite lumber applications, giving framers flexibility across a wide range of project types

Why This Product

• Purpose-built for double 2x4 framing - rather than adapting a single-member hanger, this connector is specifically engineered around the combined face width of two 2x4 boards, resulting in a cleaner, more dependable connection at the header
• Corrosion-resistant finish for lasting performance - the G90 galvanized coating is a recognized standard in protective coatings, offering meaningful resistance to the moisture exposure common on active job sites and in finished structures
• Straightforward drop-in installation - the face-mount approach eliminates back-nailing into the header end, reducing installation steps and keeping framing schedules on track
• Backed by comprehensive load documentation - published load tables covering multiple lumber species and engineered wood products mean contractors and inspectors can verify performance values without guesswork

Frequently Asked Questions

What lumber size is the U24-2 hanger designed to support?

The U24-2 is designed for double 2x4 lumber members. Its 3-1/8 in. interior width accommodates the combined face width of two 2x4 boards used as a joist in wood-framed construction.

What type of coating does the U24-2 have, and why does it matter?

The U24-2 features a Zinc Galvanized G90 coating, which provides a protective layer against corrosion. This coating helps extend the service life of the hanger in typical construction environments.

How is the U24-2 installed?

The U24-2 is a face-mount hanger, meaning it attaches directly to the face of a header or carrying member. This installation method allows the joist to be dropped into the hanger seat, simplifying framing work. Refer to the load tables and installation documentation for nail pattern and fastener requirements specific to your lumber species and project conditions.

Is the U24-2 compatible with engineered lumber products like I-joists or glulam beams?

Load values and compatibility information for I-joists, glulam, and structural composite lumber (SCL) are available in the dedicated Face-Mount Hangers - I-Joists, Glulam and SCL Tables linked in the Downloads section. Always consult the appropriate load table for your specific application and lumber type.
