Threaded rods are meant to hang straight. If they are bent sideways to reach an angled fitting, relocate the anchors or support layout so the rods carry load vertically.
['A threaded rod loses reliable load path when it is forced to bend sideways. The hanger may still look tight, but the threads and anchors are being side-loaded instead of carrying weight cleanly.', 'Move the upper anchors or adjust the trapeze so the rods drop plumb to the actual support points. The duct can be angled; the hanger load path should still be straight and stable.']
