Designed to be used with the Red Snapper quilt loading system. Experienced Longarm quilters know that using Red Snappers to attach the quilt top and backing to the frame quickly, accurately, and easily makes longarm quilting a joy. Often loading the quilt on the frame is daunting if the quilter has to pin all the edges. Red Snappers eliminate the need to pin. You can quickly press the clamp over the rod, clamping on the edge of the quilt to hold it tight and secure.
