Grommet be used purely decoratively for crafting. When used in sailing and various other applications, they are called cringles. Sometimes field workers refer to them as grunyons. If metal or another hard material has a hole made in it, the hole will probably have sharp edges. Electrical wires, cord, rope, lacings, or other soft vulnerable material passing through the hole can become abraded or cut, or electrical insulation may break due to repeated flexing at the exit point. Rubber, plastic or plastic coated metal grommets are used to avoid this. The grommet could also protect the wiring/cabling from contamination from dirt,
Cable grommet radio and the chassis or between microphone and its tripod, keeping the two components "floating" mechanically decoupled one from another to prevent a characteristic coupling called "microphonism ". Cable grommet A cable grommet is a tube or ring through which an electrical cable passes. They are usually made of rubber or metal. The grommet is usually inserted in holes in certain materials in order to protect, improve friction or seal cables passing through it, from a possible mechanical or chemical attack. A grommet can be used in furniture to protect wires, cables or cords for computer equipment or other electronic
