What is this circular track stuff called? Its used for attaching fabric with stitched in plastic piping to rigid surfaces (among other things i'm sure). You slide the part of the fabric that has the plastic tubing in the side of the track.
Haven't been able to successfully guess the correct google terms to find plain sections of this.
