The Ultimate Guide to Keystone Jacks in 2025

Overview: What Is a Keystone Jack?

Let’s start with the basics—what exactly is a Keystone Jack? If you’ve ever set up a wired network or plugged in an Ethernet cable to a wall plate, you’ve likely interacted with one, even if you didn’t realize it. A Keystone Jack is a small, modular, snap-in connector used in networking and telecommunications. It’s a critical component for terminating cables (like Ethernet cables) and connecting them to wall plates, patch panels, or surface mount boxes.

Keystone Jacks come in various types, designed for different cables like CAT5E, CAT6, CAT6A, CAT7, and even fiber optics. They’re called “keystone” because of their standardized rectangular shape, which allows them to snap into compatible keystone openings. This makes them incredibly versatile—you can mix and match different jacks in the same wall plate or patch panel, depending on your networking needs.

Key Features of Keystone Jacks:

• Modular Design: Snap-in compatibility with wall plates and patch panels.
• Versatility: Available for Ethernet, coaxial, fiber, HDMI, and USB connections.
