Galvanized steel retaining angle for HVAC dampers

Dayton

Dayton 2TGG6 Retaining Angle HVAC Control

SKU CH-5JKD-KE3QX

Galvanised-steel retaining angle for horizontal or vertical damper mounting, meeting UL 555 standard

  • 20-gauge galvanised steel resists corrosion
  • UL 555 listed for fire-damper compliance
  • Mounts horizontally or vertically for flexible installation
  • 6 3/4 in height fits standard ductwork
  • 9 3/4 in width covers typical damper frames

Product Identity

The Dayton 2TGG6 is a galvanised steel retaining angle designed for HVAC damper installations. It suits contractors and maintenance teams who need a code-compliant mounting bracket for fire and smoke dampers.

Thermal and Power Profile

This passive component generates no heat, draws no power and produces no noise during operation. Its 20 gauge galvanised steel construction withstands the temperatures present in ducted systems without degradation.

Included Hardware Impact

The bracket meets UL 555 requirements, allowing inspectors to verify damper compliance without additional documentation. Vertical and horizontal mounting options reduce the need for separate brackets on mixed-orientation duct runs.

Questions about this item

How is the 20 ga galvanized steel retaining angle mounted in horizontal or vertical orientation?

The retaining angle installs horizontally or vertically as a damper frame component using the pre-punched mounting holes; the common mistake is reversing the flange direction so the damper blade cannot seat fully against the stop.

Will the galvanized coating on this 20 ga steel angle require recoating or replacement over time?

The 20 ga galvanized steel construction provides corrosion resistance for the damper assembly; under normal HVAC conditions the zinc coating lasts the life of the damper without scheduled maintenance.

At what temperature does the UL 555 rating limit sustained operation of this retaining angle?

UL 555 certifies the assembly for fire-damper use; the retaining angle itself has no fusible link and no temperature limit — the damper's fusible link determines the release temperature.
