ABSTRACT:
This invention is an improved screen means for greenhouses and similar structures. Cam locks are provided preferably on both the upper and lower edges of the screen means, and are mounted on strong backs which in turn are secured to the structure itself. This arrangement eliminates loose spots, wrinkling, wind flapping, and similar problems that are common to screen means of this general type.
