Catalog # Description
2178-L/S-FR FLAME-RETARDANT SPLICE CASES
Designed for use in vault and building applications, the 3M 2178-L/S-FR splice
cases are molded with a flame-retardant material that allows these closures to
pass Telcordia Technologies (Bellcore), UL and various global specifications that
require a flame-retardant rating. The new material increases the resistance of
the closure to the effects of sprays and release agents used for easier re-entry.
2178-L/S FIBER OPTIC SPLICE CASES
The 3M 2178-L/S fiber optic splice case is ideal for outside plant, underground,
aerial, pedestal and direct buried applications. The cases are made of a tough
chemical-resistant material with a gasket seal. The 2178-L/S requires no special
tools or complicated training materials and stands up to even the most severe
conditions of moisture, vibration and extreme temperatures.
