    I would think Grainger, you might try spinning by hand with power off and visually check, use a stick, pencil or something for reference as you would a dial indicator. If it made contact with something while spinning, then it may need to be bent back forward, you can get lucky and save Time and Money.

    If you cannot get it bent back correctly it is better to replace with a EXACT pitch and EXACT diameter. This is extremely important so the fan moves the correct amount of air and the blade does not overload the motor.
