The Simpson THA422 Adjustable Hanger for 4x Floor Truss is a heavy-duty framing connector built to deliver reliable support beneath floor trusses, joists, rafters, and beams. Engineered by Simpson, this hanger features extra-long straps that can be field-formed on site, giving crews the height adjustability they need to fine-tune truss positioning without reaching for a separate product. Whether the job calls for a top-flange or face-mount installation, this connector adapts to the framing condition at hand - making it a practical, single-product solution across a wide range of structural applications.

Key Features

• Dual installation compatibility (top-flange or face-mount) - gives contractors the flexibility to adapt to different framing conditions on the same job site without switching products
• Extra-long field-formable straps - allow height adjustability to be dialed in on site, reducing the need for custom or special-order components
• 16-gauge steel construction - provides the structural strength and rigidity expected in demanding floor truss applications
• G90 zinc galvanized finish - delivers enhanced corrosion resistance to help the hanger hold up in tough construction environments over the long term
• 3-5/8 in. seat width sized for 4x floor trusses - ensures a proper, secure fit that supports load transfer the way the connection is designed to perform

Why This Product

• One hanger, two installation methods - the ability to switch between top-flange and face-mount installation means fewer SKUs to stock and more options when framing conditions change mid-project
• Field-adjustable height without custom fabrication - the extra-long straps can be formed directly on site, saving time and labor when truss positioning needs to be fine-tuned during installation
• Built for longevity with G90 galvanized protection - the zinc galvanized coating goes beyond basic corrosion resistance, helping this connector maintain structural integrity in demanding environments where moisture exposure is a concern
• Trusted Simpson engineering made in the United States - backed by a manufacturer with a well-established line of structural connectors, giving builders confidence in product consistency and code-relevant performance

Frequently Asked Questions

What installation methods are supported by the THA422?

The THA422 can be installed as either a top-flange hanger or a face-mount hanger, giving contractors and builders flexibility depending on the specific framing conditions on the job site.

What fasteners should be used to install the THA422?

For top-flange installation, install with 16d and 10d common nails. For face-mount installation, install with 16d common nails.

Why does the THA422 feature extra-long straps?

The extra-long straps on the THA422 are designed to be field-formed, allowing height adjustability so the truss position can be fine-tuned on-site. This also provides top-flange hanger convenience without requiring a separate product.

What corrosion protection does the THA422 offer?

The THA422 is coated with a G90 zinc galvanized finish, which provides enhanced corrosion resistance suitable for demanding construction environments.
