The Continuum Gliding Rail Kit lets you expand your quilting reach by moving fabric build–up to maximize your work area throughout the quilting process. This innovative quilting frame add–on for long–arm quilting works like a take up rail that moves back and forth with the motion of your quilting machine. The Gliding Rail adds up to 4–6 inches to your stroke and works to keep your block size consistent. When quilting normally, the layers gather on your take–up rail, taking up space and reducing block size.
