Open Toe, Even feed foot (walking foot) for horizontal rotary hook models / 7 mm machines.  The Even feed foot "walks" over fabric to assist with smooth feeding.  Fabric can be sewn without shifting or puckering since the fabric is gripped and fed by both upper and lower feed dogs.  Works well for quilting or with materials like knit, vinyl or leather.  The open toe allows for maximum visiblity.

For Janome 7mm, low shank machines including the Sewist 740DC, Sewist 780DC, DC1050, 3160QDC, 4120QDC, and 5300QDC.
