The Simpson THA418 Adjustable Hanger for 4x Floor Truss is a heavy-duty connector from Simpson built to deliver reliable support and true field-adjustable flexibility for 4x floor truss applications. Its extra-long straps can be field-formed on the job site, letting installers fine-tune the vertical position of the truss during framing rather than committing to a fixed height in advance. Whether the framing situation calls for a top-flange or face-mount approach, this single hanger adapts to both - making it a practical, versatile choice for residential and light commercial floor framing projects.

Key Features

• Dual installation options (top-flange or face-mount) - one hanger covers two common installation scenarios, reducing the need to stock separate connectors for different framing conditions
• Extra-long straps that can be field-formed - allows height adjustability on site so the exact vertical placement of the floor truss can be determined during installation, not before
• 16-gauge steel construction - delivers the structural rigidity needed for load-bearing floor truss connections without excessive bulk
• G90 zinc galvanized finish - provides extra corrosion resistance, helping the hanger hold up in framing environments where moisture exposure is a concern
• 3-5/8 in. seat width sized for 4x floor trusses - engineered to match the specific member size, ensuring a proper fit and full load transfer at the connection point

Why This Product

• Built-in height adjustability solves a common field challenge - because the straps are field-formed rather than preset, installers can determine the exact truss elevation during framing without cutting corners or fabricating custom solutions
• Two hangers in one saves time and material costs - the ability to install as either a top-flange or face-mount connector means a single product handles varied framing conditions, streamlining what needs to be on the truck
• Heavy-gauge steel with corrosion-resistant coating built for longevity - 16-gauge construction paired with a G90 galvanized finish means this connector is engineered to perform over the life of the structure, not just at the time of installation
• Engineered specifically for 4x floor truss framing - the seat width and overall geometry are matched to 4x floor truss members, so installers get a purpose-built fit rather than a generic connector adapted to an application it was not designed for

Frequently Asked Questions

Can the THA418 be used as both a top-flange and a face-mount hanger?

Yes. The THA418 is designed to be installed as either a top-flange or a face-mount hanger, giving installers flexibility depending on the specific framing application and job-site conditions.

What fasteners are required to install the THA418?

For top-flange installation, use 16d and 10d common nails. For face-mount installation, use 16d common nails. Always use all specified fasteners to achieve the rated load capacity.

How does the height adjustability of the THA418 work?

The THA418 features extra-long straps that can be field-formed, allowing the installer to adjust the height location of the truss on-site. This makes it well suited for applications where the exact vertical positioning of the floor truss needs to be determined during installation.

What corrosion protection does the THA418 provide?

The THA418 is coated with a G90 zinc galvanized finish, which provides extra corrosion resistance and makes it suitable for use in environments where moisture exposure is a concern.
