Fourth rail and attachment kit for the Q'nique frame. This great accessory offers greater control of your batting layer and keeps it off the floor. Using the fourth rail will keep the fabric clean from any small particles that may accumulate by letting it fall to the floor. Small particles can cause many problems when stitching that could interfere with the thread and normal operation of the machine.
*Note: This is only compatible with mid arm or long arm quilting machines that have a larger throat space.
