TinnerFlow™2nd YearHangers, Supports & AnchorsStop and get direction
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.
A hanger strap pulling at an angle can ride across a sharp flange, drive, or raw sheet edge. As the duct moves or loads up, that edge can cut the strap and create an overhead drop hazard.
Rework the support so the load path is vertical and clean. Use rods, trapeze, swivel hardware, saddles, or approved shims where needed so the support does not bend, saw, or side-load the duct.
Use this as training guidance. Foreman direction, approved drawings, project specs, manufacturer instructions, employer safety policy, and AHJ/code requirements always control the final answer.
