An electrical device cover comprises a base with an opening in a back wall of the base sized to receive an electrical device and a lid coupled to the base at a first base end through a hinge, the lid pivotable between and open position and at least one closed position. The base comprises a track and a notch in a side of the track extending away from the first base end. A first end of the lid in a closed position is adjustable generally parallel to the back wall of the base toward and away from a second base end. A lid pin extends from the lid towards the track when the lid is in a closed position. In each closed position the lid pin seats in the at least one notch of the track when the first lid end is selectively adjusted toward the second base end.
