Dayton galvanised steel retaining angle for HVAC dampers

Dayton

Dayton 2TGH7 Retaining Angle HVAC Control

SKU CH-2CVH-PW2TK

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

  • Galvanised steel construction resists corrosion for long service life
  • 20 gauge thickness provides rigid support for damper assemblies
  • Meets UL 555 safety standard for fire damper installations
  • Mounts horizontally or vertically to suit duct layout
  • 15 3/4 inch square profile fits standard damper frames

Retaining Angle for Damper Mounting

The Dayton 2TGH7 retaining angle secures HVAC dampers in both horizontal and vertical orientations. It is built for installers who need a single bracket that works regardless of airflow direction. The galvanised steel construction resists corrosion in duct environments. This part suits commercial and industrial ductwork projects where mounting flexibility matters.

20-Gauge Galvanised Steel Thickness

The bracket uses 20-gauge galvanised steel, which determines its rigidity and corrosion resistance. This thickness governs whether the angle can hold the damper weight without deformation over time. UL 555 listing confirms it meets the fire-damper standard required by many building codes. Select this item only if the project specification calls for 20-gauge material.

Sustained Load Behaviour in Duct Systems

Under continuous airflow pressure the 20-gauge steel maintains its shape without permanent deflection. The galvanised coating protects the surface during long exposure to humidity and temperature cycling. No fusible link is integrated, so the angle relies on the damper assembly for fire response. The bracket performs consistently whether mounted horizontally or vertically.

Questions about this item

What does the 15 3/4 inch dimension mean for fitting this angle in a duct?

The retaining angle measures 15 3/4 inches in both height and width, so it fits a square opening of that size when mounted vertically or horizontally.

What does the UL 555 standard cover for this galvanised steel angle?

UL 555 certifies the angle for use in fire dampers, confirming the 20-gauge galvanised steel meets the required fire-resistance criteria.

How do I mount the angle vertically or horizontally on a damper frame?

The angle is designed for both orientations; fasten the 20-gauge galvanised steel flange to the damper frame using appropriate screws or bolts for the duct material.
