ABSTRACT:
An open bottomed trapezoidal box having horizontally outwardly extending flanges at the free edges is provided at intervals with clips which join the horizontal flanges and which join successive lengths of the linear open box sections. The linear sections may be straight, curved on one or more radii, or angular, for flexibility in forming any outline. Alternate embodiments of the clip are shown. The clip may be used in straight lengths whether the sections are curved, angular, or straight.
