Aircraft contain complicated electrical systems that are used to transmit data and signals to power up electrical devices through a complex assembly of wires both within and between systems. Since wires are an intrinsic component of all modern aircraft, they should be shielded to protect their core from getting damaged, especially from the flayed ends of the holes through which they are threaded. This is where grommets, not to be confused with eyelets since they share similar functions, come into the picture. Grommets are made of metal, rubber, or plastic, and they are used to protect the holes through which the wires pass. In contrast, eyelets are used to stabilize the sharp edges around the holes. Thus, seeing how grommets and eyelets are fundamental to aircraft safety, this blog shall shed more light on the functionalities of each and explore the differences between them.
