The present invention includes a device and method of manufacture of the device. The device includes frame system and a rigid panel adapted to selectively cover an opening of a walled structure. The frame system includes a top rail and two side rails that couple to the walled structure. Each rail consists of a pair of oppositely disposed L-shaped bends and an intermediate flat panel body method. An L-shaped member couples to the flat panel, cooperating with one L-shaped bend to form a U-shaped channel, which adapts to slideably receive a rigid panel member consisting of plexiglass. A bottom rail releasably couples to the two side-rails to hold the rigid panel in place and allows for rapid installation and removal as needed.
