TE Connectivity Biplex plugs seal one or two cables in a (nominal) 50mm O.D. (with 4.6mm wall) duct.

Cable and duct networks from the exchange head-end to the subscriber premises need to be protected to increase their service life by making sure the duct and cable are clear and free of any water, sediment, unwanted objects, and nesting animals.

Protect your underground investment and seal it for future use.
