Four-Port Keystone Plate

The Monoprice Mid-Size Keystone Plate provides four openings for standard keystone jacks. It accepts Ethernet, HDMI, coaxial, USB, or voice and data modules to suit various connectivity needs. The UL listing confirms it meets safety and performance standards for professional installations.

Mid-Size Coverage for Clean Finishes

The mid-size form factor extends beyond standard wall-plate dimensions to hide rough cut-outs and drywall imperfections. It mounts directly to a low-voltage bracket or electrical box, requiring no specialised tools beyond a screwdriver. Impact-resistant thermoplastic construction resists cracking during installation and long-term use.

Supports Four Jacks with Flexible Layout

The plate accommodates up to four keystone inserts, allowing mixed signal types in a single gang location. It runs out of capacity when all four ports are populated or when a project demands more than four connections at one outlet. Builders needing higher port density must use multiple plates or a larger distribution panel.
