Ideal Industries Wing-Nut Insulated Wire Connector Yellow 100 pk

The IDEAL Wing-Nut Wire Connector provides an easy, secure grip when connecting a wide range of wires. The specially designed contoured wings make for extra torque and quick work on any electrical job. The wide range, live-action spring is flexible enough to handle small combinations with ease but then expands to accept large combinations when you need it. It can also be reused on same size or larger combinations for quick and easy circuit changes and additions.
