Product Description
The Simpson DGT Top-Flange Fire Wall Hanger is a patent-pending, load-tested connector purpose-built for multifamily and multilevel Type III residential construction where fire wall separation is required. Sized for 2-5/16 in. x 18 in. engineered wood joists, this top-flange hanger carries a two-hour fire rating tested per ASTM E814 and certified under Intertek Design No. SST/WPCF 120-01, making it a code-compliant solution for demanding fire-rated framing applications. Its innovative design allows two layers of 5/8 in. gypsum board to be slipped into place after framing is complete, and it is the first fire wall hanger engineered for installation with a power nailer - helping crews save time and keep projects on schedule.
Key Features
- Power nailer compatible, code listed for 1-1/2 in. and 2-1/2 in. nails - the first fire wall hanger designed for power-driven installation, so crews can fasten quickly and consistently before drywall goes up, reducing labor time on the framing stage.
- Two-hour fire rating for 2x4 or thicker walls, rated for both sides - meets fire wall performance requirements on either face of the wall, giving builders confidence in code compliance across a wide range of Type III residential projects.
- Top-flange design for back-to-back installation on 2x6 (min.) walls - allows hangers to be installed on opposite sides of the same wall without conflict, streamlining layout in multifamily corridor and party-wall assemblies.
- Accommodates two layers of 5/8 in. drywall after framing is complete - the hanger's clearance space lets drywall crews slip gypsum board into position without modifying or removing structural connectors, keeping workflows efficient.
- Tested per ASTM E814, certified under Intertek Design No. SST/WPCF 120-01 - independent third-party certification supports plan-check submittals and simplifies approval on fire-rated assemblies.
- 12-gauge steel with G90 zinc galvanized coating - heavy-gauge construction delivers structural load capacity while the galvanized finish provides corrosion resistance in exposed framing environments.
Why This Product
- Designed to speed up fire-rated framing without sacrificing compliance - as the first fire wall hanger engineered for power nailer use, it lets crews move faster through the framing phase, a real scheduling advantage on multifamily and multilevel residential projects where fire wall connections are required at scale.
- Simplifies drywall sequencing on fire wall assemblies - because the top-flange hanger leaves room for two layers of 5/8 in. gypsum board to slide in after framing, contractors do not have to coordinate drywall installation around connector placement, reducing rework and trade conflicts.
- A single hanger model rated for both sides of the wall - the DGT's ASTM E814-tested, two-hour fire rating applies to fire wall use on both faces, so builders can specify one connector for the full assembly rather than sourcing separate products for each side.
- Wide size range and expert technical support - the DGT series is offered across multiple member sizes, making it straightforward to match the right hanger to the joist dimension on hand, and Simpson backs every product with technical support for field and engineering questions.

Frequently Asked Questions
What is the fire rating for the Simpson Strong-Tie DGT2.37/18, and what wall thickness does it apply to?
The DGT2.37/18 carries a two-hour fire rating that applies to 2x4 or thicker walls. It has been tested according to ASTM E814 and is fire rated for use on both sides of the wall, with certification under Intertek Design No. SST/WPCF 120-01.
What nail sizes are approved for installing the DGT2.37/18?
The DGT2.37/18 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 installation requires (6) nails in the top, (2) 1-1/2 in. nails or (4) 2-1/2 in. nails in the face, and (6) 1-1/2 in. nails in the joist.
Can the DGT2.37/18 be installed with a power nailer?
Yes. The Simpson Strong-Tie DGT is the first fire wall hanger designed for installation with a power nailer. This feature saves time before drywall is hung, helping keep construction schedules on track without sacrificing fire-rated performance.
How does the top-flange design accommodate drywall installation?
The innovative top-flange design of the DGT2.37/18 allows two layers of 5/8 in. gypsum board (drywall) to be slipped into place after framing is complete. It also enables back-to-back installation on 2x6 (minimum) walls, providing flexibility in multifamily and multilevel construction layouts.
