Cooper Wiring Devices 2138W-BOX – Frequently Asked Questions

1) What does the "combination" cutout on the Cooper 21 Series wallplate actually cover?
The 21 Series combination wallplate has a mixed cutout configuration, meaning one opening pattern for a switch and another for a receptacle on the same plate. Use it where a single box holds two different device types side by side. If both devices in the box are the same type (two toggles, or two duplex receptacles), you want a matching two-gang toggle or duplex plate instead, not a combination cutout.
2) Will a standard-size wallplate cover an older box with a slightly oversized or chipped drywall opening?
These are standard size, not oversized or jumbo. Standard plates cover the device and the normal cut around it, but they leave a ragged or overcut drywall opening showing. For patched or oversized cutouts, step up to an oversized/jumbo plate in the same color. The 21 Series plate measures 4.5 inches on its long dimension.
3) Which Cooper 21 Series white combination wallplate model numbers are available?
Three models in white: 2138W-BOX, 2157W-BOX, and 2173W-BOX. They differ by which combination of device cutouts is punched into the plate, so order by the model number that matches the devices already in your box rather than by description alone.
4) Is thermoset a better choice than nylon or standard plastic wallplates for a high-traffic building?
Thermoset is the tougher option for corridors, break rooms, classrooms, and rental turns. Once cured it does not soften, and it resists cracking, fading, and impact better than standard plastic covers, so the plate stays white instead of yellowing behind a lamp or near a window. Nylon plates flex more and are harder to crack outright, but thermoset holds color and rigidity over long service.
5) I'm standardizing every plate in a building on white. Does the Cooper 21 Series match across different device types?
That is the point of the 21 Series. The family runs the same white finish and the same plate profile across multiple cutout configurations, so a combination plate in one room sits flush and color-matched next to single toggle or duplex plates from the same series elsewhere. For a property manager doing a whole-building refresh, ordering all plates out of one series is what keeps the finish uniform.
6) Do Cooper 21 Series wallplates come with mounting screws?
Wallplate screws are supplied with the device in standard practice, and plates in this class use the usual 6-32 wallplate screw thread that threads into the yoke of the switch or receptacle. If you are reusing an existing device and the old screws are stripped or painted over, pick up matching white-head 6-32 wallplate screws so the heads blend with the plate.
7) Can I use this wallplate in a commercial office, or is it residential only?
Both. The 21 Series combination plate is used for residential switch and receptacle coverage, commercial office and retail electrical finishing, and light industrial installations. Typical jobs are new construction, remodel wiring, and multi-device rooms where every opening needs the same finish.
