An angled hanger strap is cutting on a 45-degree duct run
Hangers should carry load cleanly without sawing on sharp metal. If a strap is angled and cutting on a flange, stop and rebuild the support with a proper vertical load path.
Do not leave a support strap rubbing across a sharp flange lip under load.
Check
Look for straps touching sharp flanges or raw edges.
Check whether the hanger is carrying load at an angle instead of straight down.
Inspect the strap for cuts, tears, or stretched holes.
Rebuild with a vertical rod/trapeze/saddle support if needed.
Hold the area if overhead support is questionable.

Say this to your foreman
The support strap on this sloped/45 run is pulling across a sharp flange and starting to cut. I stopped loading it. Do you want this rebuilt with rods and a trapeze support?
