Part # FOSC 400 B4, Flame Retardant Fiber Optic Splice Closures On Colonial Teltek

FOSC 400 FR fire resistant, fiber optic splice closures are made with a flame retardant material and can be used for splices in cable vaults and buildings.

All FOSC 400 closures have an easy-to-use mechanical clamping system for the dometo base seal. Cable ports are sealed with heat shrink tubing installed with a hot air gun. One size of cable seal can be used on any size or type of cable, in any round port and on any closure. New cables can be installed without disturbing existing cables or splices.

FOSC 400 closures are truly versatile and reliable platforms for any fiber optic cable terminations, outside and inside.
