3M 2178 Fiber Optic Splice Closure

A full line of closures and accessories designed to protect fiber optic facilities in any environment. The 3M Fiber Optic Splice Closure 2178 family has earned its reputation for reliable protection of fiber optic facilities. Now, the 2178 family includes new models and configurations for more flexibility to meet the complex needs of today's fiber optic networks.

  • Complete Product Family: 7 distinct models with different configurations including flame retardant options.
  • Future-Proof Solutions: 2178 family has scalability that allows you to expand when needed, but you can defer that investment because of the product standard options and availability.
  • Easily Re-Enterable Designs: A reusable gasket makes tool-less re-entry easy, while bolted halves provide greater security than dome closures.
