12-inch Round Duct Hanger

The Ductmate GRRDH12GA20 is a galvanised-steel hanger sized for 12-inch nominal round duct. It is built for HVAC contractors and mechanical installers who need a code-compliant support that meets SMACNA standards.

Suited for SMACNA-compliant jobs

Installers working to SMACNA requirements on residential or light-commercial gas-vent systems will find the 260 lb load rating and 20-gauge thickness appropriate. Projects that specify heavier-gauge hangers, larger duct diameters, or non-round profiles should select a different model.

260 lb load capacity at 20 gauge

The hanger carries a 260 lb rated load while using 20-gauge steel and a 1-inch strapping slot. That single figure determines whether the part satisfies the structural requirements of the current duct-support schedule.

Questions about this item

What duct diameter and strapping width does this 12-inch hanger accept?

It fits a nominal 12-inch round duct and is compatible with 1-inch wide strapping for suspension.

How do you mount the galvanized-steel hanger, and which step is often missed?

Loop the 1-inch strapping through the hanger, secure it to the structure, then tighten around the duct; the missed step is confirming the 260-lb load limit before final torque.

When should the 20-gauge steel hanger be inspected or replaced?

Check for corrosion, deformation or loose strapping after any system vibration event or at each scheduled ductwork inspection; replace if the 13-1/2-inch height shows sag or metal fatigue.
