Pass & Seymour WPB1 – Frequently Asked Questions

1) Can a Pass & Seymour WPB blank wallplate be used outdoors on an exterior box?
Yes. The WPB Series blank cover is an aluminum weatherproof plate intended for both interior and exterior device boxes, and it ships with a gasket and mounting screws so the opening seals against weather. It is the right choice for sealing an unused box on an outside wall, in a wet or damp location, or anywhere a bare indoor plastic plate would not hold up.
2) What gang sizes does the Pass & Seymour WPB blank wallplate come in?
Two: 1-gang (WPB1) and 2-gang (WPB2). Both are the same satin-finish aluminum plate with a universal aluminum mounting plate that suits interior or exterior boxes. If you have a three- or four-gang opening, this series will not cover it; a stainless option like the Mulberry 97151, which covers 1 through 4 gang, handles the wider openings.
3) I need to blank off a 2-gang box I'm abandoning during a remodel. Is the WPB2 the right part?
Yes, if the box stays in place and you need it covered and sealed. WPB2 is the two-gang blank in the WPB Series, aluminum with a gasket and screws included, and it works on an interior or exterior box. Code still requires the box be accessible, so a blank cover is the correct way to close an abandoned device opening rather than drywalling over it.
4) What is a stainless steel alternative to the Pass & Seymour WPB blank wallplate?
The Mulberry 97151 box mount blank wallplate is a 430 stainless steel cover offered in 1-gang through 4-gang sizes. The Pass & Seymour WPB plates are aluminum with a satin finish and cover 1-gang and 2-gang openings as WPB1 and WPB2. Choose the Mulberry if you need a 3-gang or 4-gang blank or want to match stainless devices already in the wall; choose the WPB if you want the aluminum satin look and the gasket and mounting screws that ship with it.
5) Does the WPB blank cover come with a gasket and screws, or do I have to buy them separately?
Both are in the box. Every WPB configuration is supplied with a gasket and mounting screws, so nothing extra is needed to close up the opening. Order the gang size that matches the box: WPB1 for a single-gang opening, WPB2 for two-gang.
6) Is the WPB blank wallplate UL and CSA listed for commercial work?
Yes, both. Every WPB configuration is UL Listed and CSA Listed, which covers inspection requirements on residential and commercial jobs on either side of the border.
7) Will a brushed aluminum blank plate corrode on an outdoor wall?
Aluminum is the point here. The WPB body is aluminum with a satin finish, chosen to resist corrosion through repeated outdoor exposure. If your spec calls for stainless instead, the Mulberry 97151 box-mount blank is 430 stainless steel. For dry interior-only locations, a thermoplastic nylon plate such as the Leviton PJ23-E is the usual commercial-grade choice.
8) What part numbers do I order for the Pass & Seymour WPB blank cover?
Two numbers cover the series: WPB1 for the single-gang blank and WPB2 for the two-gang. Finish and material are the same on both, aluminum with a satin finish, so gang size is the only decision.
9) Which blank wallplate should I standardize on for a mix of indoor and outdoor boxes?
The Pass & Seymour WPB1 and WPB2 are aluminum blanks supplied with a gasket and mounting screws and are UL and CSA Listed, which makes one part number workable on both interior device boxes and exterior or damp location boxes. The Leviton PJ23-E is a commercial grade thermoplastic nylon two-gang blank and the Mulberry 97151 is 430 stainless in 1-gang through 4-gang; if your facility standard is a plastic plate indoors and stainless in wider ganged runs, those cover those cases separately rather than as one part.
10) Is a midway size blank plate the same as the Pass & Seymour WPB1?
No. The Leviton PJ23-E is a midway size blank plate in thermoplastic nylon, a two-gang box mount cover. The Pass & Seymour WPB1 is a single-gang aluminum weatherproof blank with a satin finish. Midway refers to a plate dimension larger than standard, so a midway plate will not drop in where a WPB1 single-gang aluminum cover is specified.
11) Will a satin aluminum blank match the other plates on my wall?
The WPB plates are aluminum in color with a satin, low-glare finish, so they read as brushed metal rather than painted. They sit well next to stainless or other metal device plates. If the rest of the wall is white or ivory plastic, the aluminum will stand out; a nylon plate like the Leviton PJ23-E is the better visual match in that case.
12) Are Pass & Seymour WPB wallplates made in the USA?
Yes. The WPB Series blank wallplates list the United States as country of origin, which matters on government and institutional jobs carrying domestic-sourcing requirements.
