The Simpson Concealed-Flange Heavy Face-Mount Hanger HUC5.125/16 is a heavy-duty structural connector engineered for demanding face-mount joist-to-header connections in both residential and commercial construction. Its concealed header flange design sets it apart in exposed framing conditions, delivering clean, finished lines where visible hardware aesthetics are a genuine consideration alongside structural performance. Built from heavy-gauge galvanized steel in the United States, this joist hanger is a reliable choice for heavy structural framing connections that require enhanced load capacity and elevated safety factors.

Key Features

• Concealed Header Flange Design - Hides the hanger flanges behind the header, resulting in cleaner visible lines that keep exposed framing and finished architectural environments looking polished rather than cluttered with visible hardware.
• Heavy-Gauge 14 ga. Steel Construction - Provides the robust, long-lasting structural performance needed for heavy framing connections where load capacity and safety margins are critical requirements.
• Galvanized Finish - Delivers corrosion resistance that helps extend the service life of the connector, particularly important in framing environments where long-term durability is essential.
• Face-Mount Configuration - Allows the hanger to attach directly to the face of the header, simplifying installation in both new construction and retrofit framing projects without requiring special header preparation.
• Broad Application Range - Approved for heavy structural framing connections, exposed architectural conditions, and face-mount joist-to-header use in residential and commercial construction, making it a versatile connector across multiple project types.

Why This Product

• Aesthetics and Strength in One Connector - The concealed flange design solves a common problem in exposed framing: structural connectors that compromise the finished look. This hanger handles heavy loads while keeping visible lines clean, so builders do not have to choose between performance and appearance.
• Purpose-Built for Heavy Structural Demands - Constructed from 14 ga. (68 mil) steel with a galvanized finish, this hanger is sized and rated for connections that go beyond standard light-duty hangers, giving contractors confidence on projects with demanding load and safety requirements.
• Trusted Simpson Engineering - Simpson is a recognized name in structural connectors, and this hanger reflects that commitment to precision engineering, making it a dependable specification for structural designers and framing contractors alike.
• Versatile Fit for Residential and Commercial Projects - Approved applications span residential and commercial construction, including architectural settings where hardware visibility is a design concern, giving this connector broad utility across a wide range of job types.

Frequently Asked Questions

What does the "concealed flange" design mean for this hanger?

The concealed header flange design hides the hanger flanges behind the header, resulting in cleaner visible lines. This makes the HUC5.125/16 particularly well suited for exposed framing and finished architectural environments where aesthetics matter alongside structural performance.

What material and gauge steel is used in the HUC5.125/16?

The HUC5.125/16 is constructed from 14 ga. (68 mil) steel with a factory-applied galvanized finish. The heavy-gauge construction provides robust, long-lasting structural performance along with corrosion resistance for durability.

How does this hanger differ from a standard joist hanger?

The HUC5.125/16 is a heavy-duty hanger engineered for structures that require additional strength and higher safety factors compared to standard joist hangers. Its face-mount design mounts directly to the face of the header, and the concealed flange further distinguishes it from typical hangers that have exposed flanges visible after installation.

Where is the HUC5.125/16 manufactured?

The HUC5.125/16 is manufactured in the United States, produced to consistent quality standards as a domestically made structural connector.
