Monoprice Inc. Mid-Size Keystone Plate 3 Port Black UL Rack

3-Port Keystone Plate

The Monoprice Mid-Size Keystone Plate accepts up to three keystone jacks for voice, data, audio, or video connections. Its mid-size format covers a larger wall area than standard plates, hiding imperfections around junction boxes. UL listing confirms compliance with industry safety and quality standards. The durable construction resists cracking, fading, and wear for long-term use.

Keystone Jack Compatibility

The plate provides three universal openings that accept standard keystone inserts for copper or fibre terminations. Each port supports a single jack, so the total connection count is limited to three distinct services. No active electronics, shielding, or signal conditioning are included; performance depends entirely on the jacks and cabling chosen by the installer. The mid-size footprint does not change the keystone form factor.

Installation Scope and Limits

The three-port layout suits single-gang locations needing multi-service drops such as Ethernet, telephone, and coax in one plate. It cannot accommodate more than three jacks, so larger patch fields require additional plates or a higher-density panel. The mid-size dimensions help cover oversized cut-outs but will not fit standard single-gang boxes if the mounting holes do not align. Professional termination tools are still required for the jacks.
