Whitecap Industries 3904WP White Rubber Grommet, 3-3/8 Inch Outer Diameter (Pair)

The Whitecap Industries 3904WP is a white rubber grommet sized to a 3-3/8 inch outer diameter, sold as a pair. Rubber grommets like this are used on boat decks and hulls to line a drilled pass-through hole, protecting wiring, hoses, or cables from chafing against a raw metal or fiberglass edge while helping to seal out water at the pass-through point. The white color is chosen to blend with light-colored deck and hull surfaces rather than standing out as a dark accessory. Being made of rubber, the grommet is flexible enough to seat into a drilled hole and grip its edges, and rubber's natural resistance to water and UV exposure makes it suited to exterior marine use. Because it is sold as a pair, one package supplies two matching grommets, useful for boats with two identical pass-through points (such as matching port and starboard wiring runs) or for keeping a spare on hand. At 0.05 pounds for the pair, it is a lightweight, small-hardware item meant to be ordered alongside other deck hardware and fitted during routine wiring, plumbing, or hose installation and repair work.
