4-Port Keystone Wall Plate
The Monoprice Standard Size Keystone Plate provides four openings for keystone inserts, allowing installers to combine Ethernet, HDMI, coaxial, or telephone jacks in a single gang box. It is built from high-impact thermoplastic with a gray finish that resists scratches and fading. UL listing confirms it meets safety requirements for structured cabling projects.
Suits Custom Multi-Media Drops
This plate suits professionals and DIY installers who need a clean, organised termination point for mixed signal types in residential, office, or commercial settings. It is not for installations that require more than four ports in a single-gang footprint or for surface-mount boxes that do not accept standard keystone inserts.
Four Keystone Openings
The defining specification is the four-port capacity, which sets the maximum number of keystone jacks the plate can hold. Buyers must match their planned connection count to this limit; projects needing five or more connections will require a larger plate or an additional gang box.

Questions about this item
Does the plate come with any keystone jacks or mounting screws?
The package includes only the 4-port keystone wall plate; keystone inserts and mounting screws are sold separately.
Should I choose the black or the grey finish for a standard US single-gang box?
Both colours share the same standard-size footprint and four-port layout, so the choice is purely cosmetic.
What does the UL marking on this wall plate tell me about its use in a real installation?
UL listing confirms the thermoplastic plate meets US safety standards for use in standard electrical boxes.
