Review on Safety Technology International STI 13020FR Polycarbonate by Antonio Liu

This cover is made by Safety Technology Int. does what it should. An acoustic alarm sounds when the lid is opened, which is a good chance of preventing the fire brigade from miscalling. You just have to wait many months. I ordered 3 STI-13020FR plugs on 16th September and 1 more on 18th September now on 22nd October and they (Revain) will probably send another one soon. When I placed the order they said there were 2 in stock. But it was weeks before they shipped just 1 of these.
