what is the tip to tip measurement out to the mounting fins
You can find the measurements here in the instruction manual. Look at SF20C3 in manual: INSTRUCTION MANUAL
are the shutters manual or automatic?
The shutters on this fan are considered gravity type. This means there is no motor, and they open and close as the fan is on or off.
