The Simpson THAC422-2 Galvanized Adjustable Concealed-Flange Truss Hanger for Double 4x22 is a heavy-duty wood connector from Simpson engineered to support trusses and beams in wood framing systems. This U-shaped truss hanger features extra-long, straight straps that allow the height position of the truss to be field-adjusted on site, making it well suited for framing applications where precise vertical placement is critical. Concealed flanges keep the hanger profile tight to the surrounding structure, enabling use in restricted or confined spaces where standard flanged hangers cannot fit. The G90 zinc galvanized coating provides reliable corrosion resistance for demanding installation environments.

Key Features

• Top-flange or face-mount installation compatibility - gives installers the flexibility to choose the method that best suits the framing conditions on site, reducing the need for multiple hanger types.
• Extra-long straps for height adjustability - allow the truss height location to be set in the field without cutting or modifying the hanger, saving time and reducing material waste during installation.
• Dense nail pattern in the straps - provides more nail placement options and makes top-flange installation straightforward, accommodating varying site conditions without compromising fastening integrity.
• Min./max. nailing installation options - allow contractors to match the fastening schedule to the load requirements of the application, offering practical versatility across different project specifications.
• Concealed flanges - keep the hanger profile low in tight or restricted spaces where exposed flanges would interfere with adjacent framing members or finished surfaces.
• 14-gauge steel construction - delivers the structural strength needed to handle the load demands associated with supporting double 4x22 truss and beam members.
• Zinc galvanized finish (G90) - protects the steel against corrosion in moisture-exposed framing environments, helping the connector maintain performance over the life of the structure.

Why This Product

• Field-adjustable height without modification - the extra-long straps let framers dial in the exact vertical position of the truss after installation begins, eliminating costly repositioning or rework when conditions change on site.
• Two installation methods in one hanger - support for both top-flange and face-mount applications means this single connector can handle a wider range of framing scenarios, reducing the inventory of specialized hangers a crew needs to carry.
• Built for tight spaces other hangers cannot reach - the concealed-flange design allows secure truss support in confined framing cavities where a standard hanger with exposed flanges would not clear adjacent structure.
• Corrosion-resistant finish for long-term reliability - the G90 zinc galvanized coating is well suited for framing environments where moisture exposure is a concern, helping protect the structural connection from degradation over time.
