Monoprice Inc. Standard Size Keystone Plate 3 Port Black UL

Three-Port Keystone Wall Plate

This standard single-gang keystone plate provides three openings for snap-in jacks, enabling a tidy termination point for Ethernet, HDMI, coaxial, audio or voice connections in homes or offices. The durable ABS construction resists impact and scratches, while the black finish blends with typical wall décor. It is designed for low-voltage structured wiring projects where a clean, professional appearance is required. UL listing confirms compliance with relevant safety standards for in-wall use.

Verify Box And Jack Compatibility

Confirm that the mounting location uses a standard single-gang electrical box or low-voltage bracket, as the plate dimensions follow that form factor. Ensure the keystone jacks you intend to install are standard keystone footprint modules; proprietary or oversized inserts will not seat correctly. No tools are required for jack insertion beyond a typical punch-down tool for terminating the cables behind each module.

Passive Component Thermal Note

As a passive plastic mounting plate with no active electronics, it generates no heat, produces no noise and draws no power during operation. The ABS material remains stable at normal indoor ambient temperatures. Thermal considerations apply only to the connected active equipment elsewhere in the installation, not to the plate itself.
