The Simpson THA426 Adjustable Hanger for 4x Floor Truss is a heavy-duty framing connector from Simpson built to deliver reliable support and real job-site flexibility for floor truss framing. Extra-long straps can be field-formed on site to position the truss at the exact height needed, while dual installation compatibility means the hanger works as either a top-flange or face-mount connector - adapting to framing conditions rather than dictating them. Made from 14-gauge steel with a Zinc Galvanized G90 finish, this hanger is engineered for demanding structural applications where strength and corrosion resistance both matter.

Key Features

• Top-flange or face-mount installation - gives installers the freedom to choose the mounting method that fits existing framing conditions, reducing the need for workarounds on the job site.
• Extra-long straps that can be field-formed - allow height adjustability directly on site without swapping to a different hanger size, saving time and keeping the project moving.
• 14-gauge steel construction - provides the heavy-duty structural integrity needed to handle the load demands of 4x floor truss applications.
• Zinc Galvanized G90 coating - delivers extra corrosion resistance to hold up in construction environments where moisture exposure is a concern.
• Designed for 4x floor truss members - purpose-built fit means proper load transfer and a secure, code-consistent connection without guesswork.
• Installed with 16d common nails - uses a widely available, standard fastener type that keeps installation straightforward and accessible on any framing crew.

Why This Product

• Built-in height adjustability sets it apart from fixed hangers - the field-formable straps let crews fine-tune truss placement on site without ordering a different size or stalling the schedule.
• Two installation methods in one connector - the ability to switch between top-flange and face-mount configurations means one hanger covers multiple framing scenarios, reducing the number of SKUs a contractor needs to stock.
• Heavy-gauge steel with purpose-matched sizing - the 14-gauge build and 4x floor truss-specific seat width combine to deliver a structurally sound connection that handles real floor loading without compromise.
• G90 galvanized protection for long-term durability - the corrosion-resistant finish helps the hanger maintain its structural integrity over time, even in moisture-prone or treated-lumber environments.
