The Simpson 4-1/8 x 9-1/2 Concealed-Flange Heavy Face-Mount Hanger is a heavy-duty joist and beam connector built for structures requiring additional strength and higher safety factors. Its concealed header flanges keep mounting hardware hidden from view, making it equally well-suited for exposed architectural framing where clean visible lines matter as much as structural performance. Whether the application is residential or commercial construction, this face-mount hanger delivers the load capacity and finished appearance that demanding projects require.

Key Features

• Concealed Header Flanges - Hide the mounting flanges from sight so exposed framing maintains clean, finished visible lines without sacrificing connection strength.
• Heavy Face-Mount Design - Engineered specifically for structures requiring additional strength and higher safety factors, going beyond what standard joist hangers provide in demanding residential and commercial applications.
• 14-Gauge (68 mil) Galvanized Steel Construction - Heavy-gauge material delivers the rigidity and corrosion resistance needed for long-term performance in structural connections.
• Configurable Seat Options - Select models can be configured with a skewable seat or a seat that slopes up to 45 deg., giving builders flexibility for non-standard framing angles without sourcing a different connector.
• Precise 4-1/8 x 9-1/2 Joist Fit - Dimensioned specifically for 4-1/8 x 9-1/2 in. joist members, ensuring a secure, properly seated connection with no field modification required.

Why This Product

• Aesthetics and strength in one connector - The concealed-flange design is purpose-built for exposed framing conditions where visible hardware would detract from the finished look, eliminating the need to choose between appearance and structural integrity.
• Built for elevated load demands - Rated for structures requiring additional strength and higher safety factors, this heavy face-mount hanger is a reliable choice when standard connectors are not sufficient for the application.
• Adaptable to complex framing geometry - The ability to configure a sloped or skewed seat connection on select models makes this hanger a practical solution for projects involving angled or non-standard joist installations.
• Consistent, quality-controlled manufacturing - Produced in the United States under Simpson quality standards, buyers receive a connector that meets the dimensional and material specifications published for this model.
