The Simpson DGT Top-Flange Fire Wall Hanger is engineered to provide robust, fire-rated connections in multifamily and multilevel Type III residential constructions. This innovative hanger ensures structural integrity while maintaining fire-resistive wall assemblies, making it an essential component for builders and contractors.
Key Features:
- Two-Hour Fire Rating: Successfully tested according to ASTM E814 standards, the DGT hanger maintains a two-hour fire-resistance rating for both 2×4 and 2×6 walls, ensuring compliance with stringent building codes.
- Efficient Installation: Designed for use with power nailers, this hanger allows for quick and secure attachment before drywall installation, streamlining construction timelines.
- Drywall Accommodation: The top-flange design provides space for two layers of 5/8″ gypsum board to be installed after framing, preserving the integrity of fire-rated wall assemblies.
- Versatile Application: Suitable for back-to-back installation on minimum 2×6 walls, offering flexibility in various construction scenarios.
Installation:
- Fasteners: Use all specified fasteners as per the manufacturer’s guidelines. The hanger is compatible with both 1-1/2″ and 2-1/2″ power-driven or hand-installed nails.
- Mounting: Install the DGT hanger similarly to standard top-flange hangers. Ensure that stud wall-plate splices occur at stud locations for optimal support.
- Additional Support: For I-joist applications, web stiffeners are required to maintain structural integrity.
- Steel Header Installation: When attaching to a steel header, weld the DGT hanger using four 1/8″ x 1-1/2″ fillet welds and secure with six joist nails to achieve a download capacity of 1,700 lbs. Ensure face flanges have full backing.
Applications:
- Multifamily Residential Buildings: Provides fire-rated connections essential for apartment complexes and condominiums.
- Commercial Structures: Ensures compliance with fire safety standards in offices and retail spaces.
- Type III Construction: Ideal for buildings requiring non-combustible exterior walls with interior wood framing.
- Retrofit Projects: Suitable for upgrading existing structures to meet current fire-resistance requirements.
NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
