I'm checking round duct saddle tap orientation at [location]. I found smaller round duct connecting to larger round main through saddle fitting. Saddle tap on round main: top or side? Need reinforcement collar or support for this branch size?

Stop if

Hold point on round duct saddle tap orientation: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't install on bottom of supply ducts. Don't cut without verifying reinforcement. Don't use tap too large for main diameter.

Check
