Single-rod band hanger

Before you start

• Confirm the approved support detail, actual duct weight, support spacing, attachment substrate, hardware size, corrosion protection, and any insulation, seismic, vibration, or rooftop requirements before installation.
• Confirm the band diameter matches the duct and the rod, anchor, nuts, and washers match the approved load.
• Inspect the split ring, hinge, latch, rod threads, and hardware for damage.
• Check that the band will support the duct body without landing on a joint.

Lay it out

1. Mark the overhead anchor and duct support point.
2. Keep the rod plumb unless the approved detail shows otherwise.
3. Place the band clear of slip joints, fittings, and dampers.

Set and support it

1. Install the approved anchor and threaded rod.
2. Open and position the band around the duct.
3. Support the duct during band adjustment.

Make the connection

2. 2

   Close the band around the duct body.

3. 3

   Connect the band to the threaded rod with the specified hardware.

4. 4

   Adjust the nut to final elevation.

5. 5

7. 7
