Damper Retaining Angle

The Dayton 2TGG4 is a UL 555 listed retaining angle designed for fire and smoke damper installations. It suits contractors and facility technicians who need code-compliant hardware for horizontal or vertical mounting orientations. The 20 ga galvanised steel construction provides the structural rigidity required in commercial HVAC systems.

20 ga Galvanised Steel

The single specification that determines fit is the 20 gauge galvanised steel thickness. This dimension fixes the angle’s stiffness and its compatibility with the damper frame assembly. Verify that the damper manufacturer specifies 20 ga material before ordering, as a different gauge will not meet the tested assembly requirements.

Horizontal or Vertical Mounting

Installation is straightforward because the angle accepts both horizontal and vertical mounting without modification. The most common error is selecting the wrong gauge, which voids the UL 555 listing for the damper assembly. Confirm the gauge requirement on the damper submittal sheet before fastening the angle in place.

Questions about this item

What does the UL 555 rating mean once the retaining angle is installed?

The UL 555 listing confirms the angle meets fire-damper safety standards for use in rated assemblies.

How does the 20 ga thickness affect the installation?

The 20-gauge galvanised steel provides the structural rigidity required to secure damper blades in vertical or horizontal mounts.

What clearances are needed to mount this 5 3/4 inch angle?

The angle measures 5 3/4 inches by 5 3/4 inches, so allow at least that footprint plus fastener access for horizontal or vertical mounting.
