How often are loose connections in punchdown keystones the cause of install delays or service callbacks? Eliminate this potential trouble spot with our new Keystone Couplers. Simply terminate the cable with the Platinum RJ45 connector of your choice, plug it into the back of the Keystone Coupler, then snap the Coupler into a wall plate or surface mount box. For even more customization, combine with our unloaded patch panels for fast wiring and total flexibility.
