10 inch diameter 12 Volt Bell This sucker is LOUD and still works well !!I used it for an Alarm Bell for my house back in the 1970s.It has been just sitting around for years, unused.Can be hooked up either way: + to either wire, - to other.As can be seen from photos, it is scratched in several places.The volume/level of sound can be adjusted by loosing the bolt on top and rotating the relay mechanism on the inside
