Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 2 in. x 11-7/8 in. Engineered Wood is a patent-pending joist hanger from Simpson purpose-built for multifamily and multilevel Type III residential construction where fire-rated wall assemblies are required. Load tested and fire rated, this top-flange hanger accommodates 2 to 2-1/16 in. x 11-7/8 in. engineered wood members and is the first fire wall hanger of its kind designed to install with a power nailer - helping crews complete framing faster and keep construction schedules on track. Its innovative design leaves room for two layers of 5/8 in. gypsum board to be slipped into place after structural framing is complete, and it carries a two-hour fire-resistant rating tested in accordance with ASTM E814 for use on both sides of the wall.
Key Features
- Power nailer compatible and loads tested for 1 1/2 in. and 2 1/2 in. nails - the first fire wall hanger designed for power-driven installation, reducing labor time before drywall is hung while remaining code listed for hand-installed fasteners as well
- Two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01 (ASTM E814) - applies to 2x4 or thicker walls and is valid on both sides of the wall, giving builders a tested and listed solution for fire wall assemblies
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - allows paired hangers to be set simultaneously, streamlining workflow in multifamily framing applications
- Space for two layers of 5/8 in. drywall after framing is complete - eliminates the need to coordinate drywall and framing simultaneously, supporting a cleaner construction sequence
- Made from 12-gauge steel with a G90 zinc galvanized finish - delivers the structural strength and corrosion resistance required for long-term performance in residential construction environments
- Wide range of sizes available in the DGT product line - simplifies specification and procurement by offering a consistent hanger family across multiple joist dimensions
- Made in the United States and backed by expert technical support - provides builders confidence in product availability and access to engineering assistance when it matters most
Why This Product
- The only fire wall hanger built for the power nailer - because the DGT was specifically designed for power-driven installation, framing crews can complete hanger installation faster than with conventional fire wall hangers, helping multifamily projects stay on schedule before drywall begins
- A fully tested, code-listed fire wall solution in one component - with a two-hour fire-resistant rating tested to ASTM E814 and listed under Intertek Design No. SST/WPCF 120-01, contractors get a single hanger that satisfies both structural and fire assembly requirements without additional engineering workarounds
- Designed around the drywall sequence, not against it - the top-flange configuration accommodates two layers of 5/8 in. gypsum board installed after framing, eliminating scheduling conflicts between trades and reducing the risk of rework on fire-rated assemblies
- Consistent, familiar Simpson fastener patterns with flexible nail options - compatibility with both 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails means crews can use the tools and fasteners already on the job site without sourcing specialty hardware

Frequently Asked Questions
What is the fire rating of the Simpson DGT2.1/11.88, and what wall thickness does it apply to?
The DGT2.1/11.88 carries a two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01, tested in accordance with ASTM E814. This two-hour fire rating applies to 2x4 or thicker walls and is valid for use on both sides of the wall.
Can this hanger be installed with a power nailer?
Yes. The Simpson DGT fire wall hanger is the first of its kind designed for installation with a power nailer. It is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails, offering flexibility and speed on the job site.
How does the top-flange design accommodate drywall installation?
The DGT's top-flange design provides dedicated space for two layers of 5/8 in. gypsum board (drywall) to be slipped into place after framing is complete. This allows contractors to finish structural framing first, then install drywall without interference from the hanger, keeping construction sequences efficient.
What fasteners are required to install the DGT2.1/11.88?
Installation requires (6) 0.148 in. x 1-1/2 in. OR 0.148 in. x 2-1/2 in. nails in the top flange; (2) 0.148 in. x 1-1/2 in. nails OR (4) 0.148 in. x 2-1/2 in. nails in the face; and (6) 0.148 in. x 1-1/2 in. nails in the joist.
