Pass & Seymour SSO8 Jumbo 1-Gang 302/304 Stainless Steel Wallplate, Brushed Finish, Duplex Receptacle Opening

The Pass & Seymour SSO8 is a Jumbo 1-Gang wall plate machined from Type 302/304 stainless steel with a duplex receptacle opening, built for environments where standard plastic or metal covers fall short. This non-magnetic alloy carries 18% chromium and 8% nickel for superior corrosion resistance, finished at a nominal .032" thickness with a clean brushed surface. It is cULus Listed, making it a dependable choice for demanding commercial and industrial device coverage where atmospheric exposure is a concern.

Key Features

  • Jumbo 1-Gang Configuration: Sized for a single duplex receptacle opening with extra coverage area beyond a standard plate.
  • Corrosion-Resistant Alloy: Type 302/304 stainless steel with 18% chromium and 8% nickel content delivers superior resistance to corrosion.
  • Non-Magnetic Construction: Nominal .032" thickness stainless steel for durability without magnetic interference.
  • Brushed Finish: Clean, consistent brushed surface that also accepts paint to match plastic plates when needed.
  • Duplex Receptacle Opening: Pre-punched to accept standard duplex receptacle devices.
  • Finish-Matching Hardware: Packaged in protective film with finish-matching screws included.
  • Customizable: Can be silk-screened or engraved, with custom punching available in over 300 opening styles.

Why Pass & Seymour?

Pass & Seymour engineers the SSO8 from true 302/304 stainless steel rather than a lighter-gauge substitute, giving installers a wall plate that holds up to washdown, humidity, and chemical exposure over the long term. The cULus Listing backs its suitability for professional, code-compliant electrical work, while the brushed finish and finish-matching screws deliver a consistent, professional appearance across a facility.

Pass & Seymour SSO8 – Frequently Asked Questions

1) Is the Pass & Seymour SSO8 an oversized plate, or will it fit like a standard duplex cover?
The SSO8 is a Jumbo (oversized) 1-gang duplex plate, measuring 5.25 by 3.5 inches with a 0.2 inch depth. That gives you extra coverage beyond a standard plate, which is what you want when the drywall or tile cut around the box is ragged or the old plate left an outline. If you need the plate to sit flush with a row of standard-size covers, a jumbo plate will look noticeably larger next to them.
2) Will the SSO8 stainless wallplate hold up in a washdown or food plant environment?
That is the application it is built for. The plate is Type 302/304 stainless with 18% chromium and 8% nickel, which is why Pass & Seymour points it at food processing plants, dairies, chemical plants, and wet or wash-down areas. Material thickness is a nominal .032 inch. For a painted steel plate in the same location you would be chasing rust bleed at the screw holes within a season.
3) Does the SSO8 fit a standard duplex receptacle?
Yes. The opening is pre-punched for a standard duplex receptacle, so it drops over any common 15A or 20A duplex device. It will not fit a decorator/rocker style device or a toggle switch, those take a different opening.
4) What is the closest alternative to the Pass & Seymour SSO8 for a single duplex receptacle if stainless steel is not required?
The Bryant P8 Series 1-Gang duplex wallplate covers the same opening - one duplex receptacle on a single gang - and is the straightforward alternative when the corrosion resistance of stainless is not part of the requirement. The SSO8 is built from Type 302/304 stainless steel with a brushed finish and is cULus listed, which is what makes it the pick for food processing, dairy, chemical, and washdown areas. For a dry office or corridor wall, the Bryant P8 duplex plate addresses the same device.
5) I need an oversized plate but for a toggle switch, not a receptacle - what should I order instead of the SSO8?
The SSO8 is punched for a duplex receptacle opening only, so it will not cover a toggle switch. For a 1-gang toggle switch plate, the Mulberry 41020 from the 4102 Series is a toggle switch plate rather than a receptacle plate. Note that the Mulberry 41020 is a gas burner red plate, so it is used where the switch needs to be identified by color rather than blended into a stainless wall.
6) Do the mounting screws come with the stainless wallplate or do I order them separately?
Screws are in the box, and they are finish-matched to the brushed stainless so they do not stand out. The plate ships in a protective film to keep the brushed face unmarked until it is installed.
7) What is the difference between a stainless wallplate like the SSO8 and a painted steel plate?
It comes down to where it is going. The SSO8 is 302/304 stainless with a brushed finish for corrosive, humid, or wash-down areas. If the location is a dry office or corridor and you just want a durable metal plate in white, a painted steel option like the Mulberry 86401 (8640 Series steel 1-gang, white) or the Mulberry 76432 in a 2-gang combination is the simpler buy. Stainless is what you pay for when atmosphere is the problem, not appearance.
8) I need a 1-gang duplex plate but not in stainless. What else is there?
For a standard 1-gang duplex cover, Bryant's P8 Series is the straight alternative. If you need a mid-size plate rather than jumbo or standard, Bryant's PJ Series covers M-size wiring devices. Neither is a stainless corrosion-resistant plate, so for a dairy, chemical plant, or wash-down room stay with the 302/304 stainless SSO8.
9) The SSO8 is a 1-gang plate - what do I use when the box has two devices side by side?
The SSO8 is a Jumbo 1-Gang plate and covers one device opening. For a two-device box, the Mulberry 76432 in the 764 Series and the Mulberry 76532 in the 765 Series are both 2-gang combination wallplates in cold rolled steel with a white finish. They are a different material and finish from the brushed stainless SSO8, so if the run needs to look consistent, plan the gang count before you standardize the finish.
10) Is the Mulberry 86401 steel plate an equivalent to the Pass & Seymour SSO8?
They are both 1-gang metal plates, but they are not interchangeable in appearance or in service environment. The Mulberry 86401 in the 8640 Series is a steel plate in white. The SSO8 is Type 302/304 stainless steel with a brushed finish, an alloy carrying 18 percent chromium and 8 percent nickel for corrosion resistance, which is why it is specified for chemical plants, dairies, and washdown areas. If you are matching white plates through a facility, the 86401 fits that scheme; if the concern is atmospheric or chemical exposure, the stainless SSO8 is the one built for it.
11) Can I use the SSO8 over a data or voice jack?
No - the SSO8 is pre-punched for a standard duplex receptacle device and has no modular jack provision. For low-voltage work, the Eaton 35324W is a wallplate with a 4-conductor data/voice modular jack, Type 625B4, which is the correct part for a telecom drop. The SSO8 remains the receptacle cover; the two serve different openings and are not substitutes for one another.
12) Can stainless wallplates be painted or labeled to match the rest of my facility?
The brushed surface takes paint if you need it to match plastic plates elsewhere in the building. It can also be silk-screened or engraved for circuit identification, and Pass & Seymour offers custom punching in over 300 opening styles if a standard duplex cutout is not what the device requires.
13) Is the SSO8 magnetic? I have equipment sensitive to magnetic interference.
No. The 302/304 alloy used here is non-magnetic, which matters in MRI suites, lab spaces, and around sensitive instrumentation. Plated steel plates will pick up a magnet; this one will not.
14) Is the SSO8 made in the USA?
Yes, country of origin is the United States. That matters if you are buying against a Buy American or domestic-preference clause on a government or institutional job.
15) What is an alternative to the SSO8 when the plate needs to be oversized to hide a rough wall opening?
The SSO8 is already the Jumbo size, measuring 5.25 in high by 3.5 in wide, so it gives extra coverage area beyond a standard plate for exactly that purpose. If you need an oversized plate in another line, the Bryant PJ Series is an M-size wallplate for wiring devices. Confirm the device opening matches your receptacle before ordering, since the SSO8 is punched specifically for a duplex.
16) How does the Bryant NP26W compare with the Pass & Seymour SSO8 for a 1-gang opening?
Both are 1-gang wallplates. The Bryant NP26W is part of the HWS Series. The SSO8 is the Jumbo 1-Gang stainless plate with a duplex receptacle opening, brushed finish, and finish-matching screws packed in protective film, and it can be silk-screened, engraved, or custom punched in over 300 opening styles - so if the job calls for labeled circuits or a nonstandard device cutout, that customization is on the SSO8 side.
