a ring formed by laying up a single strand of rope three times, and used originally to form eyes on the bolt-ropes of sails. It has long been replaced by the spring-loaded hank or clip-hook. Grommets have various other uses on board ship and, when the two sides of one are brought together by a serving, it forms a couple of connected eyes, always a useful article to have available on deck. Grommets were also used to hold the oars to thole pins when rowing.
