Pass & Seymour SSO13 Jumbo 1-Gang Blank Wall Plate, 302/304 Stainless Steel
The Pass & Seymour SSO13 is a Jumbo 1-Gang blank wall plate machined from Type 302/304 stainless steel and designed for box-mounted installation. Built at a .032" nominal thickness in a non-magnetic alloy, this plate is cULus Listed and finished with a brushed surface that resists corrosion in demanding environments. It is engineered for facilities that need a durable, code-compliant cover plate that can be customized to match specific job requirements.
Key Features
- Configuration: Jumbo 1-Gang blank plate, box mounted, for applications requiring a larger cover footprint than a standard 1-gang plate.
- Durable Construction: Type 302/304 stainless steel, non-magnetic, at .032" nominal thickness; the alloy contains 18% chromium and 8% nickel for superior resistance to corrosion.
- Finish: Brushed finish that is also paintable to match plastic plates for coordinated installations.
- Customizable: Can be silk-screened or engraved, and custom punched with over 300 opening styles to fit specific device configurations.
- Complete Packaging: Packaged in protective film with finish-matching screws included for a clean, ready-to-install finish.
- Family Availability: Part of a broader stainless steel plate line offered in Standard, Jumbo, and Tandem configurations, as well as special Panel plates up to 5-gangs high and 10-gangs wide.

Pass & Seymour SSO13 – Frequently Asked Questions
1) How big is the Pass & Seymour SSO13 jumbo blank plate, and will it cover a rough opening a standard plate leaves exposed?
The SSO13 measures 5.25 in high by 3.5 in wide, with a 0.2 in depth. That oversize footprint is the whole point of a jumbo plate: it covers ragged drywall cuts, old paint lines, and patched openings around a single-gang box that a standard plate would leave showing. It is box mounted, so it screws to the device box rather than to a mounting strap.
2) Is the SSO13 blank plate suitable for a food processing or chemical plant washdown area?
It is built for exactly those rooms. The plate is Type 302/304 stainless at .032 in nominal thickness, an alloy running 18% chromium and 8% nickel, which is why Pass & Seymour lists food processing plants, dairies, and corrosive-atmosphere chemical plants among its applications. It is cULus Listed. Note it is a cover plate, not a gasketed or weatherproof enclosure cover, so for direct washdown spray you still need a sealed cover assembly.
3) I need a blank cover over an abandoned outlet, but the box still has a device in it. Is the SSO13 the right part?
Only if the opening is being covered over completely. The SSO13 is a blank plate with no device cutout, so it suits a junction box, an abandoned outlet that has been safely terminated, or a future-use box. If you still need access to a switch or receptacle, you want a punched plate instead: the Bryant P8 Series is a 1-gang duplex cover, and the Eaton 35324W carries a 4-conductor Type 625B4 data/voice jack.
4) I need a 1-gang blank cover but the device box has a switch in it - what should I order instead of the Pass & Seymour SSO13?
The SSO13 is a blank plate, meaning it has no device opening at all, so it will not work over a toggle switch. For a switch opening in a single gang, the Mulberry 41020 is a 1-gang toggle switch plate from the 4102 series. Order the blank SSO13 only where the box is being covered with no device in service.
5) What is the difference between the Pass & Seymour SSO13 and a steel 1-gang plate like the Mulberry 86401?
Both cover a single gang box. The SSO13 is Type 302/304 stainless steel at .032 inch nominal thickness with a brushed metallic finish, in a jumbo footprint measuring 5.25 in high by 3.5 in wide. The Mulberry 86401 is a steel 1-gang wallplate in the 8640 series finished in white. Choose the stainless SSO13 where corrosion resistance and a metal appearance matter, and the white steel plate where a painted white finish is wanted.
6) I have a duplex receptacle to cover - is the SSO13 the right plate?
No. The SSO13 is a blank plate with no device cutout. For a duplex receptacle in a single gang, the Bryant P8 series 1-gang duplex wallplate is configured with the duplex opening. The SSO13 can be custom punched with over 300 opening styles if a stainless plate is required, but as stocked it is blank.
7) For a food processing or washdown area, is a white steel plate acceptable instead of the SSO13?
The SSO13 is specified for corrosive atmospheres because its Type 302/304 alloy carries 18 percent chromium and 8 percent nickel for corrosion resistance, and it is cULus Listed. The white plates in the comparable range, such as the Mulberry 86401 steel 1-gang and the Mulberry 76432 cold rolled steel 2-gang, are painted steel rather than stainless. For food processing plants, dairies, and chemical plants, the stainless SSO13 is the plate built for that duty.
8) Does the SSO13 come with mounting screws, or do I need to order them separately?
Screws are in the package, and they are finish matched to the plate. Pass & Seymour ships it in protective film with the screws included, so nothing else is required to hang it on a standard single-gang device box.
9) Will a magnet stick to this stainless wall plate? I need non-magnetic covers near sensitive equipment.
No. The SSO13 uses non-magnetic 302/304 stainless, which is what makes it acceptable in MRI suites, labs, and other areas where ferrous hardware is restricted. Steel plates like the Mulberry 8640 Series 1-gang are cold rolled or plated steel instead and will hold a magnet.
10) My opening needs two gangs, not one - what covers a 2-gang box instead of the SSO13?
The SSO13 is a jumbo 1-gang plate and covers only one gang. For two gangs, Mulberry offers the 76432 in the 764 series and the 76532 in the 765 series, both cold rolled steel 2-gang combination wallplates in white. Note those are combination plates with device openings rather than blanks.
11) Will a Bryant PJ series plate work as a substitute for the Pass & Seymour SSO13 on an oversized opening?
They serve a similar purpose but are not the same part. The SSO13 is a jumbo 1-gang stainless steel plate at 5.25 in by 3.5 in, sized to cover more wall than a standard 1-gang plate. The Bryant PJ is an M-size wallplate for wiring devices. Confirm the device opening before substituting, since the SSO13 is blank.
12) I need to cover a box that will hold a data jack later - is the SSO13 or the Eaton 35324W the better pick?
If the box is being closed off with no device, the SSO13 blank stainless plate is the fit. If the jack is going in now, the Eaton 35324W is a wallplate with a 4-conductor data/voice modular jack, Type 625B4, so the jack comes as part of the plate. The SSO13 has no opening and would need to be replaced or custom punched when the jack is added.
13) Can I paint this stainless plate to match the white plastic plates on the rest of the wall?
Yes. The SSO13 ships with a brushed finish that Pass & Seymour states is paintable to match plastic plates, so you can blend one stainless cover into a run of painted or plastic devices. It can also be silk-screened or engraved if you are labeling circuits or equipment.
14) Is the Pass & Seymour SSO13 made in the USA?
Yes, country of origin on the SSO13 is the United States, which matters if you are working a job with domestic sourcing requirements on the spec.
15) Can I get this plate punched for a non-standard device or pilot light?
Custom punching is offered on the Pass & Seymour stainless line with over 300 opening styles, so odd device combinations, pilot lights, and equipment cutouts can be accommodated. The SSO13 itself ships blank. For a factory-marked switch plate in a different vein, Mulberry's 41020 is a red 1-gang gas burner toggle plate.
16) Is the Bryant NP26W an equivalent to the Pass & Seymour SSO13?
They are both single gang wallplates but not interchangeable in appearance or material. The Bryant NP26W is from the HWS series. The SSO13 is a jumbo blank in brushed 302/304 stainless with finish-matching screws included, and it is paintable if it needs to coordinate with plastic plates on the same run. Match the device opening and the gang footprint before swapping either way.
