This drill hole on the iFLO® hanger can be used in an instance where the tape on the back of the hanger may not work for you due to the configuration or location of your air handler. This drill hole allows you to mount your iFLO® to drywall or a wooden stud.
Note: If you do not have a wooden stud available to install the iFLO® you will need to use a drywall anchor to fasten the hanger.
The drill hole is also designed for commercial installation to allow mounting with a flat-head sheet metal screw directly to the air handler. This should only be done by an experienced HVAC technician.
