Fluke Networks 10113000 4-Wire Modular Adapter;

Fluke Networks in-line banjo modular adapters allow you to easily complete testing and obtain circuit access on working lines without disrupting service. Each adapter has a number of advantages including angled copper contacts that prevent alligator clips from coming off during testing, small holes in each contact for easy probe insertion, and clear circuit markings on the sides and bottom of the unit. Our standard Modular Adapter has four clearly marked contacts for proper termination, and provides field technicians with a quick connection to modular telephone jacks using any standard butt-set equipped with spring clips.
