This Preformed Line Products Strength Member Bobbin Kit (vendor part 80808633, Millennium Part #522202) is designed for LCC (low-profile) dome splice closures, providing the bobbin hardware needed to anchor and manage cable strength members inside the closure. Properly securing strength members protects fiber optic cable splices from tension and pulling stress after installation, helping maintain long-term signal integrity in aerial, buried, and pedestal-mounted closures. This kit is stocked in Millennium's Fiber Optic Splice Trays & Cable Entry Kits category, giving splicing crews a factory-matched accessory for completing PLP LCC dome closure installations correctly the first time.
