The Simpson Concealed-Flange Heavy Face-Mount Hanger HUC310-2 is a double heavy concealed-flange face-mount joist hanger from Simpson, engineered for structural framing applications where both elevated load capacity and a clean finished appearance are priorities. Designed as a heavy-duty double hanger, it is well suited for exposed framing conditions where the hardware remains visible and the quality of construction is on full display.

Key Features

• Concealed header flanges - flanges sit behind the header rather than in view, delivering cleaner visible lines in exposed framing without sacrificing structural integrity
• Heavy-duty double hanger configuration - combines two hanger seats in a single unit to increase load-bearing capacity for demanding structural applications
• 14-gauge (68 mil) steel construction - provides the robust, reliable performance required in applications that call for additional strength and higher safety factors beyond standard hangers
• Galvanized finish - offers corrosion resistance to help maintain long-term performance in typical framing environments
• Face-mount installation design - attaches directly to the face of the header, simplifying placement and alignment during framing

Why This Product

• Strength where standard hangers fall short - the heavy-duty double configuration is purpose-built for structural conditions that require greater load capacity and additional safety factors, making it a dependable choice for critical framing connections
• A finish that works in exposed spaces - the concealed-flange design hides hardware behind the header, so the hanger does not visually interrupt finished or visible framing - a clear advantage over standard face-mount options with exposed flanges
• Domestic production from a trusted brand - the HUC310-2 is a Simpson product made in the United States, reflecting consistent quality control and manufacturing standards
• Versatile fit for a range of heavy framing needs - whether used in residential or commercial structural framing, the combination of heavy-gauge steel, galvanized finish, and concealed-flange geometry addresses both performance and aesthetic demands in a single connector

Frequently Asked Questions

What makes the HUC310-2 different from a standard joist hanger?

The HUC310-2 features concealed header flanges, which hide the flange behind the header for a cleaner appearance in exposed framing. It is also built to heavier specifications - using 14-gauge (68 mil) steel - to meet applications requiring additional strength and safety factors beyond what standard hangers provide.

What is the gauge and material of the HUC310-2?

The HUC310-2 is manufactured from 14-gauge (68 mil) steel with a galvanized finish, providing both structural integrity and corrosion resistance in typical framing environments.

Is the HUC310-2 appropriate for use in exposed framing where appearance matters?

Yes. The concealed-flange design is specifically intended for use in exposed conditions, as it provides cleaner visible lines compared to standard hangers with visible flanges.

Where is the HUC310-2 manufactured?

The HUC310-2 is a product of the United States.
