Field check
Standard work. Do it right, keep moving.
Anchor the boot/diffuser independently so duct twist does not control the finished ceiling line.
['Round branch duct can put twisting force into a light plenum boot. If the boot is not independently supported, the diffuser line rotates and looks sloppy in the finished ceiling.', 'Loosen the connection, square the slot with the ceiling line, add approved boot support/hold-down clips/wires, and reconnect the duct without twisting tension.']
