A cover assembly comprises an outer metal frame and an inner metal frame in a nested configuration. A window plate is trapped between these two frames such that the frames do not take away much of the window area. The two metal frames can be fixed in place by spot welding using a laser or the like. As such, the assembly does not require tape adhesive or ultra-sonic welding to fix in place. A plurality of clips and hooks extended from the inner metal frame for providing grounding to a device that uses the cover assembly.
