Super Feeder 6' cord and jack plug. This cord can be hooked to the terminal strip underneath one feeder with the plug inserted into the jack of another feeder to trigger multiple feeders with one power adapter. The cord can also be used with a power pack of your own to make sure it fits the feeder's side power jack. EACH FEEDER COMES WITH A POWER ADAPTER, BUT MAKE SURE THE POWER ADAPTER HAS SCREW TERMINALS TO BE ABLE TO USE IT AS A REPLACEMENT CORD. THIS IS JUST AN ADDITIONAL OR REPLACEMENT CORD IF YOU WOULD LIKE ONE. IF YOU NEED THE KOI POND POWER ADAPTER, ORDER ITEM ACAC-12KOI
