Product Description
The Simpson DGT Top-Flange Fire Wall Hanger is a patent-pending, load-tested connector engineered for multifamily and multilevel Type III residential construction where fire-rated framing connections are required. Designed to carry 2 1/2 in. x 18 in. engineered wood joists, this hanger delivers a two-hour fire-resistant rating tested to ASTM E814 and is approved for use on both sides of a fire wall. Its innovative top-flange design accommodates two layers of 5/8 in. gypsum board slipped into place after framing is complete - and as the first fire wall hanger built to work with a power nailer, it keeps crews moving and projects on schedule. Made in the United States from 12-gauge steel with a G90 galvanized finish, it combines durability, code compliance, and installation efficiency in a single connector.
Key Features
- Compatible with power nailers and hand-nailing - load tested and code listed for 1 1/2 in. and 2 1/2 in. power-driven or hand-installed nails, so crews can use the tools already on site without changing workflow.
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) - tested to ASTM E814 and rated for use on both sides of the wall, helping projects meet fire assembly code requirements with a single listed connector.
- Top-flange design supports back-to-back installation on 2x6 (min.) walls - allows hangers to be set on both sides of a shared wall, making it well suited for party-wall and fire-wall assemblies in multifamily construction.
- Built-in clearance for two layers of 5/8 in. drywall - gypsum board slides into place after framing is complete, keeping the construction sequence clean and eliminating the need to work around installed drywall.
- Two-hour fire rating applies to 2x4 or thicker wall assemblies - broad wall-thickness compatibility means the connector works across a range of structural wall configurations without requiring special detailing.
- 12-gauge steel construction with G90 galvanized coating - heavy-gauge steel delivers structural strength while the zinc galvanized finish provides corrosion resistance for long-term performance in framed assemblies.
- Wide range of DGT sizes available - the DGT line spans multiple joist dimensions, making it straightforward to select the right hanger for each framing condition on a single project.
Why This Product
- The first fire wall hanger designed for power-nailer installation - this purpose-built compatibility with pneumatic nailers reduces installation time before drywall goes up, helping keep multifamily and multilevel projects on schedule without sacrificing code compliance.
- A complete fire-wall framing solution in one connector - with a two-hour fire-resistant rating tested to ASTM E814 and clearance for two layers of 5/8 in. gypsum board on both sides, this hanger addresses fire-rated assembly requirements at the framing stage rather than requiring retrofit solutions later.
- Backed by independent third-party fire testing - the Intertek-listed rating gives engineers, inspectors, and contractors a verifiable, code-referenced credential to cite during plan review and inspection, reducing approval uncertainty on fire-wall assemblies.
- Domestic manufacture and Simpson technical support - made in the United States and backed by expert service and technical support, the DGT is a dependable specification for architects and contractors who need consistent product quality and accessible product guidance.

Frequently Asked Questions
What fire rating does the DGT2.56/18 carry, and how was it tested?
The DGT2.56/18 carries a two-hour fire-resistant rating under Intertek Design No. SST/WPCF 120-01. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall. The two-hour fire rating applies to 2x4 or thicker wall assemblies.
Can the DGT2.56/18 be installed with a power nailer?
Yes. The DGT is the first fire wall hanger designed specifically for installation with a power nailer. It is also load tested and code listed for hand-installed nails. Both 1-1/2 in. and 2-1/2 in. nails (0.148 in. diameter) are approved for use, giving installers flexibility on the job site.
How does the top-flange design accommodate drywall installation?
The 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 the framing and hanger installation to be finished before drywall work begins, helping to keep the construction schedule on track.
What joist size and wall thickness is the DGT2.56/18 designed for?
The DGT2.56/18 is designed for 2-1/2 in. x 18 in. engineered wood joists, with a seat width of 2-9/16 in. The top-flange design supports back-to-back installation on walls that are 2x6 (minimum) in thickness, and the two-hour fire rating applies to 2x4 or thicker wall assemblies.
