Dayton

Dayton 2TGG7 Retaining Angle HVAC Control

SKU CH-VMJN-ZD6R4

Galvanised-steel damper retaining angle for horizontal or vertical mounting, 20 ga thick and UL 555 compliant

  • Galvanised steel resists corrosion for long service life
  • 20 gauge thickness provides rigid support for damper assemblies
  • Mounts horizontally or vertically to suit duct layout
  • UL 555 listing confirms fire-damper compliance
  • Retaining angle design secures damper blades in place

Product Identity

The Dayton 2TGG7 Retaining Angle is a galvanised-steel bracket designed to secure HVAC dampers in commercial and industrial ductwork. It serves installers and maintenance teams who need a code-compliant mounting component for fire and smoke damper assemblies.

Build Integration

The angle mounts in either a horizontal or vertical orientation, allowing it to adapt to the damper layout without additional fabrication. Its 20 gauge galvanised steel construction satisfies UL 555 requirements, so the assembly meets the standard without extra reinforcement or specialised fasteners.

Included Benefits

No separate hardware or fusible link is supplied with the bracket, leaving the installer to select the appropriate link temperature and mounting screws for the specific damper model. This approach keeps the component versatile across different damper configurations while maintaining compliance with the referenced safety standard.

Questions about this item

What is the material thickness of the retaining angle?

The retaining angle is made from 20 ga galvanized steel, which defines its structural rigidity under sustained load.

Does the galvanized steel construction affect heat dissipation during continuous operation?

Galvanized steel conducts heat steadily, so the angle will reach ambient temperature without creating hotspots during all-day HVAC cycling.

Which damper standard must the existing system meet for this angle to be compatible?

The angle is built to UL 555, so the damper assembly it retains must also comply with that standard for proper fit and fire-resistance performance.
