NID TJ Add A Line with Protector

Model: SA-4717-PP01


The NID TJ Add A Line with Protector is designed for simple and easy clip-in installation in virtually all industry standard NIDs, allowing for the continued use of existing infrastructure. The White colored case makes it easily identifiable from the various Splitters type modules available.

With a potted cavity and gel filled IDC connectors, this POTS bridging module is suitable for all applications, from the NID outside the house to inside wiring closets in apartments.

The NID Add A Line with Protector is environmentally sealed against the elements.
