The Noble Box Fan Frame is designed to mount to the top of your Noble Square Stall Fronts to help circulate the air in your stalls.  This fan frame is made from galvanized angle iron and is built to accept a standard 20” x 20” box fan (fan not included).  The frame and fan should mount high above the stall and be positioned 45° from the ground (no tools needed to install).  Only works with Noble Square Tube Stall Fronts or Dividers.
