The Simpson THAC426-2 Adjustable Concealed-Flange Truss Hanger for Double 4x26 is a heavy-duty wood connector from Simpson built to support trusses and beams where precise height positioning and a low-profile installation are both required. Formed in a U-shape from 14-gauge steel and finished with a G90 zinc galvanized coating, this truss hanger features extra-long, straight straps that make field adjustment of the truss height straightforward without the need for specialized tools or custom fabrication. The concealed-flange design keeps the connector tight to the surrounding structure, making it well-suited for confined or restricted framing spaces where a standard open-flange hanger would not fit cleanly.

Key Features

• Top-flange or face-mount installation - gives contractors flexibility to choose the installation method that best suits the framing layout and job-site conditions, reducing the need to source different hangers for different applications.
• Extra-long straps for height adjustability - allow the vertical position of the truss to be set in the field without cutting or modifying the hanger, saving time and reducing material waste on complex framing projects.
• Dense nail pattern in the straps - provides more placement options for fasteners and simplifies top-flange installation, giving installers greater control over nailing sequence and load distribution.
• Min./max. nailing installation options - allow the hanger to be installed with a defined minimum or maximum nail count, supporting code-compliant installations across varying load requirements.
• Concealed flanges - keep the hanger profile unobtrusive in tight or restricted spaces where exposed flanges would interfere with adjacent framing members or finished surfaces.
• 14-gauge steel construction - delivers the structural integrity needed to handle the demands of supporting a Double 4x26 truss or beam in wood framing applications.
• G90 zinc galvanized finish - provides corrosion resistance for use in environments where moisture exposure is a concern, helping the connector maintain performance over the life of the structure.

Why This Product

• One hanger, two installation methods - the ability to switch between top-flange and face-mount installation means this single connector covers a wider range of framing scenarios, reducing inventory complexity for contractors who work across varied job types.
• Field-adjustable height positioning - the extra-long straps eliminate the guesswork of fixed-height hangers by letting the truss position be set on-site, which is especially valuable in situations where as-built conditions differ from the original plan.
• Designed for tight spaces without sacrificing load capacity - the concealed-flange profile solves the common problem of fitting a structural connector into a restricted framing cavity, making this hanger a practical choice for architecturally complex or space-constrained construction.
• Corrosion-resistant finish built into the product - the G90 galvanized coating means no additional field treatment is needed to protect the connector from moisture, supporting long-term structural reliability in demanding environments.
