Product Description
The Simpson Top-Flange Fire Wall Hanger is a patent-pending, load-tested joist hanger engineered for 2 1/2 in. x 18 in. engineered wood members used in multifamily, multilevel Type III residential construction. This innovative hanger carries a two-hour fire rating tested to ASTM E814 and is fire rated for use on both sides of the wall - making it a purpose-built solution for fire wall assemblies where code compliance and construction efficiency both matter. As the first fire wall hanger designed to install with a power nailer, it accelerates the framing phase and helps keep projects on schedule by allowing drywall installation to follow structural framing without retrofitting the connector.
Key Features
- Loads tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails - gives installers flexibility to use either a power nailer or hand-nail on the jobsite without sacrificing code compliance.
- Two-hour fire rating applies to 2x4 or thicker walls - meets fire-resistant assembly requirements across a broad range of wall configurations common in Type III residential construction.
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - simplifies double-sided hanger placement at fire wall locations, reducing layout complexity and labor.
- Space for two layers of 5/8 in. drywall after framing is complete - eliminates the need to coordinate drywall and framing simultaneously, keeping trades working in sequence and on schedule.
- Two-Hour Fire-Resistant rating, Intertek Design No. SST/WPCF 120-01 - provides independently certified documentation for inspectors and code officials, supporting smooth project approval.
- Made from 10-gauge steel with a G90 zinc galvanized finish - delivers the structural strength and corrosion resistance required for long-term performance in wall assemblies.
Why This Product
- The first fire wall hanger built for power nailer installation - this design breakthrough means framing crews can set hangers at full production speed rather than slowing down for hand-nailing, directly reducing labor time before drywall begins.
- Fire-rated on both sides of the wall with certified third-party testing - the ASTM E814-tested, Intertek-certified two-hour rating gives builders and contractors the documentation needed to satisfy fire wall requirements in multifamily and multilevel Type III projects with confidence.
- Engineered specifically for fire wall framing sequences - the top-flange configuration accommodates two layers of 5/8 in. gypsum board slipped in after framing, so structural work and fire-rated finishes stay on separate, non-conflicting schedules.
- Versatile fastener compatibility without compromising load ratings - acceptance of both 1 1/2 in. and 2 1/2 in. nails, power-driven or hand-installed, means the hanger adapts to the tools and fasteners already on site rather than requiring special hardware.

Frequently Asked Questions
What fire rating does the DGHT2.56/18 carry, and how was it tested?
The Simpson Strong-Tie DGHT2.56/18 carries a two-hour fire rating. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall, holding the Intertek Design No. SST/WPCF 120-01 certification. The two-hour fire rating applies to 2x4 or thicker walls.
What nail sizes are approved for installing the DGHT2.56/18?
The DGHT2.56/18 is loads tested and code listed for both 1-1/2 in. and 2-1/2 in. power-driven or hand-installed nails (0.148 in. diameter). The specific installation pattern calls for (6) nails in the top, (2) or (4) nails in the face depending on nail length, and (6) nails in the joist.
Can this hanger be installed using a power nailer?
Yes. The DGHT is the first fire wall hanger specifically designed to be installed with a power nailer. This capability saves time before hanging drywall and helps keep construction projects on schedule, while still being approved for hand-installed nails as well.
Does the DGHT2.56/18 accommodate drywall installation after framing?
Yes. The top-flange design of the DGHT2.56/18 provides space for two layers of 5/8-in. gypsum board (drywall) to be slipped into place after the framing is complete, making it well suited for fire wall assemblies in multifamily and multilevel construction.
