Bell PBC300GY – Frequently Asked Questions

1) Will the PBC300 fit a square or rectangular weatherproof box?
No. The PBC300 is configured for round weatherproof boxes only. If the box in the wall is a square 4-inch or a rectangular single-gang weatherproof box, this cover will not line up with the mounting holes or seal the opening, and you need a cover matched to that box shape instead.
2) What is the Bell PBC300 round cover used for?
The Bell PBC300 is a blank, flat nonmetallic cover for round weatherproof electrical boxes. There are no device openings in it, so its job is to close off a round outdoor box that isn't feeding a device, keeping moisture, dust and debris out of the box and off the wiring. Common uses are sealing an abandoned exterior outlet opening, capping a round box left for future use, and closing boxes during renovation work.
3) How far does the PBC300 cover stick out from the box?
Depth is 0.35 inch, so it sits nearly flush against the box face. That matters where the box is behind a light fixture, under a deck rail, or in a tight spot beside a door casing and a deep bubble-type cover would be in the way.
4) Is a blank nonmetallic cover acceptable on an outdoor box for inspection?
The PBC300 is UL Listed and intended for weatherproof outdoor boxes, so it is the right type of part for sealing an unused round box in a wet or damp location. Nonmetallic construction also means no corrosion or rust staining on coastal and high-moisture exteriors, unlike a painted metal cover.
5) What colors does the Bell PBC300 blank cover come in?
Two: white (PBC300WH) and gray (PBC300GY). Property managers matching a run of existing exterior boxes usually pick gray for gray weatherproof boxes and white where the trim or siding is white, since the cover is the visible piece once the box is sealed.
6) Can I use the PBC300 if I want to add a receptacle or lamp later?
Yes, that is a normal use. Because the cover is solid with no device openings, it seals the box now and can be swapped for a receptacle or lampholder cover later without touching the box itself. Keep the box and its gasket surface intact and the change is just a cover swap.
