It's also a go-to choice for commercial service centers, drive-through businesses, gas stations and long residential driveways. Just plug it into a 110-volt outlet. This loud warning bell will work with up to 150 feet of hose, which must be purchased separately. The bell is inside a sturdy aluminum housing, and is about 6 inches in diameter.
