The Mini Stopper II from STI, Waterford, Mich., offers protection against physical damage (both accidental and intentional). It consists of a clear, tough polycarbonate cover and frame that fits over the protected unit. When lifted to gain access to the protected unit, its optional battery powered alarm emits a piercing 105 dB. Immediate attention is drawn to the area and a prankster will either run or be caught.
