As a professional electrician, you're likely to spend a lot of time twisting wires. This can be boring, repetitive, and time consuming. With these In-Sure 2 port connectors, you can be sure of a positive connection without the twisting action. For these connectors, you only need to make sure your wire is stripped to a half inch. After that, push it into the connecting socket, and you're good to go. The plastic coating on the outside lets you look into the unit to ensure a proper connection. From there, you can plug in the connector wherever it needs to go. Whether you're an electrician or working in IT, there are plenty of jobs around where these will serve you well.
