The Simpson Strong-Tie DGTX Top-Flange Fire Wall Hanger is a patent-pending, load-tested hanger engineered for multifamily and multilevel Type III residential construction where fire-rated wall assemblies are required. Carrying a two-hour fire-resistant rating tested in accordance with ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01, this hanger is approved for use on both sides of the wall. Its top-flange design accommodates power nailer installation before drywall is hung, and its custom-dimensioned profile - available in widths from 1-9/16" to 3-5/8" and heights from 7-1/4" to 24" - is built to accept two layers of 5/8" gypsum board directly within the hanger once framing is complete.
Key Features
- Two-hour fire-resistant rating (ASTM E814, both sides of wall) - gives builders and inspectors verified code compliance for fire wall assemblies without relying on add-on solutions or field modifications.
- Intertek certified under Design No. SST/WPCF 120-01 - provides third-party documentation that simplifies plan review and approval on multifamily and Type III residential projects.
- Top-flange design compatible with power nailer installation - allows fastening to be completed before drywall goes up, reducing hand-nailing labor and helping crews maintain framing schedules.
- Accepts 1 1/2" and 2 1/2" power-driven or hand-installed nails - gives installers flexibility to use standard fasteners already on site without sourcing specialty hardware.
- Dedicated space for two layers of 5/8" gypsum board built into the hanger profile - eliminates the need to field-cut or notch around the hanger, keeping drywall installation clean and consistent.
- 12-gauge zinc galvanized (G90) steel construction - delivers the structural strength and corrosion resistance expected in load-tested, code-listed connectors used in permanent assemblies.
- Custom-dimensioned widths (1-9/16" to 3-5/8") and heights (7-1/4" to 24") - means the hanger can be specified to match the exact joist size on a given project rather than forcing a closest-fit approximation.
- Minimum 2x4 wall support for fire rating; back-to-back installation on 2x6 minimum walls - clearly defined structural requirements make specifying the correct assembly straightforward for engineers and framers alike.
Why This Product
- Purpose-built for fire wall compliance in multifamily construction - the DGTX is load-tested and third-party certified specifically for two-hour fire-rated assemblies in multilevel Type III residential buildings, giving project teams a single connector that addresses both structural and fire code requirements at once.
- The first fire wall hanger designed for power nailer installation - this top-flange innovation lets crews fasten hangers to the framing quickly and efficiently before drywall begins, reducing installation time compared to hangers that require hand-nailing or post-drywall fastening steps.
- Accommodates finished drywall without rework - because the hanger profile is sized to receive two layers of 5/8" gypsum board, there is no conflict between the connector and the fire-rated wall assembly, eliminating a common source of field modifications and inspection delays.
- Configurable to project-specific joist dimensions - with width and height ranges that span a broad spectrum of framing sizes, the DGTX can be matched to the actual lumber used on a job rather than requiring structural workarounds, supporting cleaner detailing and more accurate load calculations.

Frequently Asked Questions
What fire rating does the Simpson Strong-Tie DGTX hanger carry, and how was it tested?
The DGTX carries a two-hour fire-resistant rating tested in accordance with ASTM E814. It is fire rated for use on both sides of the wall, and its rating is certified under Intertek Design No. SST/WPCF 120-01.
Can this hanger be installed with a power nailer?
Yes. The DGTX is the first fire wall hanger designed to install with a power nailer. It is load-tested and code listed for use with both 1-1/2" and 2-1/2" power-driven or hand-installed nails, helping save time before drywall installation.
What wall thicknesses and drywall configurations is the DGTX compatible with?
The two-hour fire rating applies to 2x4 or thicker walls. The hanger features an innovative top-flange design built for back-to-back installation on 2x6 (minimum) walls, and it provides dedicated space to accommodate two layers of 5/8" gypsum board after framing is complete.
What sizes and materials are available for the DGTX?
The DGTX is a custom-dimensioned component available in widths from 1-9/16" to 3-5/8" and heights from 7-1/4" to 24". It is manufactured from 12-gauge zinc galvanized (G90) steel for durability.
