Flat Oval Duct: Protect Shape and Use the Correct Joint System
Handle flat oval as its own system: preserve the oval shape, support the flat sides, and use the specified connector and fitting method.
Stop if
- This is flat oval from [manufacturer/system]. Which joint and support detail applies, and how do you want the shape protected during the lift?
Watch out
- Do not force round fittings onto it, treat it like rectangular TDC, or sling it where the flat sides can collapse.
Check
- Confirm manufacturer and joint type
- Check major and minor dimensions
- Support sections to prevent flattening
- Align seams and fittings without twisting
- Verify reinforcement and hanger details for the size
