- 20-gauge thickness provides structural rigidity
- 13 3/4 in square fits standard damper frames
Retaining Angle for Damper Systems
The Dayton 2TGH4 is a galvanised steel retaining angle designed to secure dampers in HVAC installations. It suits contractors and facility managers who need a code-compliant component for horizontal or vertical mounting orientations.
UL 555 Compliant Construction
The angle meets UL 555 standards with a 20-gauge galvanised steel body measuring 13 3/4 inches in both height and width. No fusible link is included, so the part relies on the damper assembly for fire-rated performance during sustained exposure.
Horizontal and Vertical Mounting Options
Pre-punched holes allow installation in either orientation without field modification. The flat profile fits standard damper frames, though installers must verify fastener spacing matches the existing ductwork pattern before securing.

Questions about this item
How much heat does the 20 ga galvanized steel angle transmit when mounted vertically all day?
The 20 ga galvanized steel construction does not generate heat; it simply holds the damper in place whether mounted vertically or horizontally.
What damper size matches the 13 3/4 in height and width of this retaining angle?
It is designed for dampers with a 13 3/4 in by 13 3/4 in frame so the angle fits the full perimeter.
Will the UL 555 rated angle work with an older damper that lacks a fusible link?
Yes, the angle carries UL 555 listing and the fusible link temperature is not applicable, so it installs on dampers without a link.
