No more will you have to wire or solder your own lead on your Panaflo fan. You can use these on untailed Panaflo fans. Available with 4 pin power supply connector or 3 pin connector. Panaflo fans come untailed or bare wire leaving you high and dry. We had these special Panaflo connectors made that plug right into the outside of the Panaflo's fan motor. Simply plug them in!
