Four-Port Keystone Plate

The Monoprice Mid-Size Keystone Plate accepts up to four keystone jacks for Ethernet, HDMI, coaxial, USB, or voice and data connections. Its mid-size dimensions cover wall cut-out imperfections for a clean, professional finish. Constructed from impact-resistant thermoplastic, it resists cracking and fading over time. The UL listing confirms compliance with recognized safety standards.

Replaces Standard Single-Gang Plates

This plate upgrades basic wall outlets by consolidating multiple media types into one larger footprint. The extra coverage hides oversized or irregular drywall openings that standard plates leave visible. The jump is worth it when a tidy, multi-service termination point is needed in homes, offices, or data centres. It suits both DIY enthusiasts and professional installers seeking a uniform look.

Four Jacks Maximum Capacity

The four-port layout comfortably handles a typical workstation mix such as network, video, USB, and voice links in a single location. It runs out when a project demands five or more connections at one wall position or when a standard single-gang plate is required to fit a tight electrical box. The thermoplastic body provides reliable retention for daily patching cycles.

Questions about this item

What wall-box opening size does the mid-size plate cover?

The mid-size form factor is wider than a standard plate to hide rough cut-outs around a single-gang box, giving extra coverage for a cleaner finish.

How do the keystone jacks secure into the four ports?

Each jack snaps in from the front with its integral latch; the step installers miss is not hearing the click, which leaves the jack loose and able to pull out.

What part will need replacement if a port breaks or a jack type changes?

Only the individual keystone jack needs swapping — the impact-resistant thermoplastic plate itself stays mounted and is UL listed for long-term service.
