Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 2x8 is a patent-pending, load-tested connector engineered for multifamily and multilevel Type III residential construction where fire-rated wall assemblies are required. Tested in accordance with ASTM E814 and fire rated for use on both sides of the wall, this top-flange hanger is the first fire wall hanger designed to install with a power nailer - saving time before drywall is hung and helping keep framing schedules on track. Made from 12-gauge steel with a G90 zinc galvanized finish, the DGT28 delivers reliable structural performance and code-compliant fire resistance backed by Simpson's expert service and technical support.
Key Features
- Power nailer compatible - loads tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - lets crews nail off hangers with standard pneumatic tools before drywall goes up, reducing labor time and keeping projects on schedule.
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) tested to ASTM E814 - provides verified, code-compliant fire resistance on both sides of the wall so inspectors and project teams can confirm compliance with confidence.
- Two-hour fire rating applies to 2x4 or thicker walls - covers a wide range of common framing scenarios in multifamily and multilevel residential construction without requiring oversized or specialty framing members.
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - allows paired hangers to be set simultaneously at fire wall locations, streamlining layout and reducing installation steps.
- Space for two layers of 5/8 in. drywall after framing is complete - lets framers finish their work first, then drywall crews slip panels into place without disturbing the structural connection or requiring rework.
- Made from 12-gauge steel with G90 zinc galvanized coating - delivers the structural rigidity needed for load-rated fire wall assemblies along with corrosion resistance suited to demanding job site conditions.
- Nominal joist size 2x8 with 1-9/16 in. seat width - sized precisely for 2x8 framing members so the hanger seats correctly and maintains the tight tolerances required for a fire-rated assembly.
Why This Product
- The first fire wall hanger built for power nailer installation - no other fire wall hanger on the market carries this distinction; crews can drive nails with standard pneumatic tools before drywall is hung, cutting installation time at a critical stage of the framing sequence.
- A single hanger size covers a wide range of fire wall applications - the two-hour rating applies to 2x4 or thicker walls, the top-flange design accommodates back-to-back pairing on 2x6 (min.) walls, and the profile accepts two layers of 5/8 in. gypsum board, making this one connector versatile enough for multiple conditions on the same project.
- Load-tested, code-listed, and third-party fire rated - verified performance under ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01 means the DGT28 arrives on the job site with the documentation builders and inspectors need for Type III residential fire wall assemblies.
- Made in the United States and backed by Simpson technical support - consistent domestic manufacturing and access to expert product support give contractors and specifiers reliable supply and answers when project details require verification.

Frequently Asked Questions
What fire rating does the DGT28 carry, and how was it tested?
The DGT28 carries a two-hour fire-resistant rating. It has been tested in accordance with ASTM E814 and is rated for use on both sides of the wall. The rating is certified under Intertek Design No. SST/WPCF 120-01 and applies to 2x4 or thicker walls.
Can the DGT28 be installed with a power nailer?
Yes. The DGT28 is the first fire wall hanger designed to install with a power nailer. It is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven nails, as well as hand-installed nails, giving installers flexibility on the job site.
How does the top-flange design accommodate drywall installation?
The innovative top-flange design provides space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after framing is complete. This allows for efficient sequencing of framing and drywall work without requiring modifications to the hanger or framing assembly.
What is the minimum wall thickness required for back-to-back installation of the DGT28?
The DGT28's top-flange design supports back-to-back installation on walls that are 2x6 (minimum) in size. The two-hour fire rating applies to 2x4 or thicker walls in single-side applications.
