The Simpson HUC48TF HUCTF Top-Flange Concealed-Flange Joist Hanger is a heavy-duty hybrid connector engineered for nominal 4x8 lumber, combining the structural benefits of both face-mount and top-mount hanger designs into a single, versatile solution. Two concealed flanges make this hanger purpose-built for end-of-wall and corner framing applications where a low-profile connection is required. Face-nailing allows the hanger to be securely attached to the structural member, while 12-gauge steel construction and a G90 zinc galvanized coating deliver the strength and corrosion resistance demanded by residential and light commercial framing projects. HUCTF-series hangers are tested, load rated, and code compliant, giving installers and inspectors confidence on every job.

Key Features

• Hybrid face-mount and top-mount design - combines the advantages of both hanger types in one connector, reducing the need for multiple product types on complex framing layouts.
• Two concealed flanges - allows installation at end-of-wall and corner locations where standard hangers cannot be used, expanding placement options without compromising structural integrity.
• Face-nailing attachment - enables secure, rigid fastening directly to the structural member for a reliable, stable connection at every installation point.
• 12-gauge steel construction - provides heavy-duty load capacity suited to demanding 4x8 joist-to-header and joist-to-beam connections in structural framing.
• G90 zinc galvanized coating - delivers proven corrosion resistance, making this hanger appropriate for use in moisture-prone framing environments.
• Slope capability up to 45 deg. - accommodates angled joist installations without requiring a separate sloped hanger, adding flexibility to roof and floor framing designs.
• Tested, load rated, and code compliant - HUCTF-series engineering meets recognized standards, simplifying approval during inspections and giving builders confidence in structural performance.
• Rough beam sizes available by special order - the hanger is not limited to standard nominal dimensions, making it adaptable to a wider range of framing scenarios.

Why This Product

• One connector, two hanger systems - the hybrid face-mount and top-mount design eliminates the need to source separate hangers for different installation conditions, streamlining material planning and reducing jobsite complexity.
• Built for tight or concealed framing locations - the concealed-flange configuration is specifically engineered for end-of-wall and corner connections where conventional joist hangers cannot be properly seated or fastened.
• Slope-ready without additional hardware - with support for joist slopes up to 45 deg., this hanger handles angled framing members in a single product, avoiding the cost and coordination of sourcing specialty sloped connectors.
• Verified structural performance - as a tested and load-rated connector, the HUCTF series meets code compliance requirements, helping projects move through inspection efficiently and giving contractors documented confidence in the connection.
