ABSTRACT:
The assembly comprises first and second tracks of extruded polyvinyl chloride plastic which, when interfaced, become a hinged clamp. When snapped or clamped together, the tracks tighten and securely clamp fabrics of varying weights. By providing relatively elongated tracks, the installation of the fabric is greatly facilitated in that extended marginal edges of the fabric can be clamped in a single clamping motion. There is no need for a special tool requiring successive stuffing of the fabric into a biased slot and the labor and time involved therewith.
