Grommets come in many different sizes and types, but the ones most often used in auto maintenance are wiring and blanking grommets. Wiring grommets are simply small rings of rubber that provide a non-abrasive surface for the holes that electrical wiring is fed through. This protects the wiring from any sharp, metal edges, preventing it or its insulation from wearing out over time. Blanking grommets, also known as blind grommets, are circular, and most commonly used to plug off holes while still allowing the option of feeding a cable through later on. It’s important that the grommets you buy fit snugly into the holes you’re working with - measure the diameter of the holes and match it up to the size shown on the packets for the best results.
