The Simpson THA422-2 Galvanized Adjustable Hanger for Double 4x Floor Truss is a heavy-duty structural connector from Simpson Strong-Tie, engineered to deliver a reliable, load-bearing connection for double 4x floor trusses in residential and commercial framing applications. Built on the THA series platform, it features extra-long straps that can be field-formed on the job site to achieve the precise truss height needed, giving installers both top-flange hanger convenience and face-mount flexibility in a single connector. Constructed from 14-gauge steel with a G90 zinc galvanized finish, this adjustable truss hanger is built to perform in demanding structural environments where strength, corrosion resistance, and installation versatility all matter.

Key Features

• Top-flange or face-mount installation - a single hanger covers two common installation methods, reducing the need to stock separate connectors for different framing conditions.
• Extra-long straps that can be field-formed - allows height adjustment directly on the job site, so trusses can be precisely positioned before final fastening without special tools or custom hardware.
• 14-gauge steel construction - delivers the structural rigidity required for supporting double 4x floor truss members under demanding load conditions.
• G90 zinc galvanized finish - provides extra corrosion resistance, making this hanger suitable for environments where moisture exposure is a concern.
• Installs with 16d common nails - uses standard, readily available fasteners so there is no need for proprietary hardware to complete the connection.

Why This Product

• Built-in height adjustability saves time in the field - the field-formable extra-long straps let framers dial in truss placement on the spot, eliminating the guesswork and rework that comes with fixed-height hangers.
• Two installation configurations in one product - the ability to switch between top-flange and face-mount use means this hanger adapts to varying site conditions without requiring a different SKU.
• Heavy-gauge steel with proven corrosion protection - 14-gauge construction paired with a G90 galvanized coating means the connector maintains structural integrity over time, even in moisture-prone framing environments.
• Backed by Simpson Strong-Tie engineering - part of a trusted line of structural connectors designed specifically for wood framing applications, giving builders confidence in the connection's performance for double 4x floor truss support.
