The success of the SignComp™ Flexible Faced Tensioning System can be attributed to the unique Tension Clip and it's ease of application. Made from DuPont Delrin industrial plastic, it is impervious to all weather conditions . The Clip consists of 2 parts, Body and Mandrel and is applied directly to the vinyl substrate, negating the need for additional work such as pocketing or eyelets. The Clip is re-usable.
