This is an essential safety tool for every homeowner. It's a simple but sturdy steel wrench designed to shut off your main gas supply in case of an emergency, like a leak or a natural disaster. The tool has a rectangular opening that fits standard gas meter shut-off valves (the opening measures 1-1/16 inch wide by 1/2 inch high – please verify this matches your valve before buying!).
It's made from solid, heavy-duty steel so it won't bend or break when you need it most. Keep one near your gas meter (maybe in a garage or utility room) and consider giving one to a neighbor. It's a small investment for a lot of peace of mind. The pack includes two wrenches, so you can have a backup. Remember, if you smell gas, leave the area immediately and call emergency services before attempting to shut off the valve.
