A ball tension device for horizontal yarn comprising generally a body defining a vertical channel within which one or more balls can be positioned to vary yarn tension. A pair of horizontally aligned openings communicate with the bottom of the channel to provide for yarn inlet and outlet as the yarn passes through the device. Similar, ceramic inserts line the inlet and outlet openings and are angularly downwardly inclined to define a pair of opposed, angularly inclined conduits through which the yarn horizontally passes in the tensioning procedure.
