The Simpson LU24 Galvanized Face-Mount Joist Hanger is built for joist-to-header connections in wood-framed construction, delivering reliable structural support in a precision-formed, economical package. Designed by Simpson for face-mount framing applications, this hanger features speed prongs that temporarily position and secure the connector during installation, reducing handling time and keeping the workflow moving. Value engineered for strength, the LU24 is a practical choice for framers and contractors who need code-compliant performance on residential and light commercial joist connections.

Key Features

• Tested, load rated, and code compliant - gives builders confidence that every connection meets recognized structural standards without additional verification work on the job site.
• Speed prongs temporarily position and secure the connector - hold the hanger in place hands-free before fastening, speeding up installation and reducing the chance of misalignment.
• Multiple fastener selections with tested allowable loads - allows installers to use nails or Strong-Drive SD screws depending on what is on hand, without sacrificing rated performance.
• Precision-formed from 20-gauge steel - consistent dimensions mean the hanger seats squarely every time, reducing fit issues and rework during framing.
• G90 zinc galvanized finish - provides extra corrosion resistance, making the LU24 suitable for applications where moisture exposure is a concern.

Why This Product

• Speed prongs make solo installation practical - the built-in positioning feature lets one person hold, place, and fasten the hanger without a second set of hands, saving time on busy framing crews.
• Flexible fastening options mean fewer delays - because the LU series is tested with several fastener selections, installers are not locked into a single nail specification and can adapt to what is available on site.
• G90 galvanized coating adds long-term durability - the extra corrosion resistance helps the hanger hold up in crawl spaces, unconditioned framing bays, and other environments where bare steel would be at risk.
• Value-engineered design keeps material costs in check - the LU24 is purpose-built to deliver the load ratings and code compliance framers require without overbuilding, making it a cost-effective standard for high-volume joist hanger applications.
