In manufacturing or production/repair and other related industries, grommets are used to cover the rough and sharp edges of a hole in a metal junction. This is designed to protect material as it is passed through. When a wire must go through a hole in metal, Rubber grommet is the right thing to use. This type of grommet effectively and safely grips the wire.</p> Always run the wires thru a rubber grommet when it goes thru a metal firewall, floor or some sort of a tin sheet metal surface, the reason for that is because very often there is a serious fire hazard, not only because there is a sharp metal edge, sometimes too many wires are squeezed together in one hole so it is all pushed up tight against the sharp edge of the hole and every time the engine runs or hits a bump there is vibration on those wires and they are sawn away on sharp edge, eventually this can start a fire if it is not fixed properly. Stress free living knowing that you're well protected from fires or explosions!</p> <b>Rubber grommets are called a cheap insurance policy, why not make your life easily safe?
