This Preformed Line Products grommet (vendor part 8003796, Millennium Part #521918) is a solid, round, 12-hole flat grommet used to seal multiple cable entry points on a PLP dome splice closure. Installed at the closure base, it keeps fiber optic cable and strength members organized while maintaining a weathertight seal against moisture intrusion in aerial, buried, and pedestal-mounted closures. This grommet is stocked in Millennium's Splice Enclosures and Trays accessories category, giving fiber splicing crews the factory-matched sealing components needed to complete a proper PLP dome closure installation.
