The main theme in the design of this invention is to provide adequate protection while allowing for easy installation and removal without interrupting the operation of the device which is being protected. The two most important components of this invention are the use of resilient clips on the side walls with each clip having a leg extending inwardly allowing this leg to be inserted between the device and the surface, the second important component is the use of gasket material between the frame and the device to be protected. This combination allows for protection from the elements and from accidental operation even without either open end being covered.
