The Simpson HUC3.25/12TF Concealed Top-Flange Face-Mount Hanger is a heavy-duty hybrid joist hanger engineered for structural framing situations where standard hangers fall short. Designed specifically for 3-1/8 x 12 lumber members, this hanger merges the strengths of both face-mount and top-mount designs into a single connector, making it a dependable solution for end-of-wall and corner framing connections where concealed top flanges are required. Face-nailing capability allows secure attachment to the supporting member, delivering a strong and reliable connection in demanding floor and roof framing applications.

Key Features

• Hybrid Face-Mount and Top-Mount Design - combines the structural benefits of both hanger types in one connector, giving installers greater flexibility at end-of-wall and corner locations without needing separate hardware
• Concealed Top Flanges - flanges are hidden once installed, producing a cleaner finish while maintaining structural integrity in applications where exposed hardware is undesirable
• Face-Nailing Capability - allows the hanger to be fastened directly to the face of the supporting member, enabling secure connections in locations where top-nailing is not practical
• 12-Gauge Steel Construction - heavy-gauge fabrication delivers the load capacity and rigidity required for demanding structural framing connections in floor and roof assemblies
• Zinc Galvanized G90 Coating - provides a protective finish that resists corrosion over the service life of the hanger in protected framing applications
• Sized for 3-1/8 x 12 Lumber - precisely dimensioned to fit engineered lumber and timber members of this size, ensuring a consistent, snug fit that supports proper load transfer

Why This Product

• Purpose-Built for Difficult Connection Points - the concealed top-flange, face-mount configuration was specifically developed for end-of-wall and corner installations where conventional joist hangers cannot be used, making this hanger a practical solution rather than a workaround
• One Connector, Two Functions - by integrating both face-mount and top-mount hanger advantages into a single product, this Simpson hanger reduces the need to source multiple connector types for complex structural framing layouts
• Heavy-Duty Performance for Large Lumber Members - the combination of 12-gauge steel construction and precise sizing for 3-1/8 x 12 members makes this hanger well suited for substantial floor and roof framing loads that lighter connectors are not designed to handle
• Made in the United States by Simpson - manufactured domestically under Simpson quality standards, this top flange face mount hanger is a trusted choice for structural connectors in residential and commercial framing projects
