Backdraft Damper??
Multi unit building. This access was above the tub in the bathroom. The label said "Access to Cape Backdraft Damper" What is this? My guess is to prevent backdraft to each unit from multi unit ducts branching into one central trunk? So no smoke can enter this unit in case of a fire / cooking odors, etc???

Cape BackDraft Damper~the ultimate one way air flow valve

It is supposedly a better and more efficient backdraft damper than the metal butterfly types you here flopping back and forth in bath fans and other uses.
Being as it was above the tub, it may have been for the bath exhaust fan?
