Hello Robert. The Manual Lift Knob for the # FV807357 vent has a screw that goes down thru the top of the handle and attaches it to the motor assembly. If you were to remove the knob, there would be no part of the shaft that extends beyond the motor, so it sounds like this vent will work for you. view full answer...
