ICTCS stands for: InterChangeable Tubular Clamping System.

Both the ICTCS 1 & 2 attach directly to the machines existing hoop arms. (Tubular mount) They use a spring-loaded clamping chassis to hold interchangeable upper and lower clamping windows. These windows hold the fabric and backing in place during sewing.

The ICTCS 1 & 2 each offer a variety of window sizes, but the windows are exclusive to their respective system – windows for the ICTCS 1 will not fit the ICTCS 2, and vice versa.
