PLATINUM TOOLS' 202016J EZ-RJ45 CAT 6 connector and strain relief combo kit lets you quickly terminate up to fifty CAT 6 cables. The connectors are compatible with solid and stranded wires and have through holes so you can easily verify the proper wiring order. To improve electrical performance, each connector pulls the cable jacket tightly in the back, reducing the distance between the wire twists and contacts. Furthermore, strain reliefs are included for securing the rear of the connector and maintaining the bend radius of the cable.
