Product Description
The Simpson DGT Top-Flange Fire Wall Hanger for 3 1/2 in. x 18 in. engineered wood is a patent-pending, load-tested connector purpose-built for multifamily and multilevel Type III residential construction where code-compliant fire wall separation is required. Tested to ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01, this hanger carries a two-hour fire-resistant rating and is approved for use on both sides of the fire wall assembly. Its innovative top-flange design is the first of its kind engineered to accept power nailer installation, allowing crews to complete the connection before drywall goes up and helping keep framing schedules on track. Two layers of 5/8 in. gypsum board slip into place after framing is complete, streamlining the entire fire-rated assembly process.
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 the flexibility to use a power nailer or install by hand without sacrificing code compliance or load performance.
- Two-hour fire-resistant rating (Intertek Design No. SST/WPCF 120-01) tested to ASTM E814 - provides verified, third-party-certified fire protection so builders can satisfy fire wall code requirements with confidence.
- Two-hour fire rating applies to 2x4 or thicker walls - broad wall-thickness compatibility means the hanger works across a wide range of standard framing assemblies without special modification.
- Innovative top-flange design for back-to-back installation on 2x6 (min.) walls - enables paired hangers to be set on opposing sides of the wall before drywall, simplifying layout and reducing rework.
- Space for two layers of 5/8 in. drywall after framing is complete - framing crews can finish their work first and let drywall crews slide panels in later, keeping trades from stepping on each other's schedules.
- Made from 12-gauge steel with a Zinc Galvanized, G90 finish - heavy-gauge construction paired with corrosion-resistant coating delivers the structural integrity and longevity expected in occupied residential buildings.
- First fire wall hanger designed for power nailer installation - eliminates the slower hand-nailing process at the header connection, reducing labor time at one of the most repetitive steps in fire-rated framing.
Why This Product
- Code-ready fire wall compliance out of the box - the two-hour fire-resistant rating tested to ASTM E814 and certified under a recognized Intertek design number means inspectors and plan reviewers have a clear, documented path to approval on multifamily and multilevel Type III projects.
- The only fire wall hanger built for power nailer installation - because it accepts both power-driven and hand-installed fasteners at the top flange, crews can set hangers at full nailer speed before drywall, cutting installation time at scale across large floor systems.
- Designed around the real sequencing of a job site - the top-flange configuration and post-framing drywall slot mean framing and drywall trades can each work in their natural order, reducing coordination delays and keeping the project on schedule.
- Domestic manufacture backed by expert technical support - made in the United States and supported by Simpson's technical resources, this hanger is a dependable specification for contractors who need consistent product quality and reliable answers when field questions arise.
