Mulberry 40430 Steel Blank Ceiling Cover Plate, Smooth Enamel Finish, 4-Inch x 4-Inch

The Mulberry 40430 Steel Blank Ceiling Cover Plate is a 4-Inch x 4-Inch blank cover designed to close off an unused ceiling electrical box cleanly and safely.

Its compact 4-Inch x 4-Inch footprint is sized to match standard ceiling electrical boxes for a flush, professional-looking installation. Whether a ceiling box has been left over from a removed fixture or was never wired for a device, this steel blank cover fully encloses the box interior so no wiring is left exposed to the room. The smooth enamel surface gives the finished ceiling a neat, uniform look that blends in with surrounding trim and paint.

Mulberry 40430 – Frequently Asked Questions

1) Will the Mulberry 40430 blank cover fit a standard 4-inch square ceiling box?
The Mulberry 40430 is a 4 x 4 inch steel blank plate sized to match standard ceiling electrical box openings, so it caps a standard square ceiling box without modification. It has no device openings at all, so it only works where you want the box fully closed off, not where a fixture or device still needs to come through.
2) Is a blank steel cover an acceptable way to close out an abandoned ceiling junction box?
That's exactly what the 40430 is for. It's a solid opening-free steel plate that fully encloses the box interior so no wiring or splices are left exposed to the room, which is what you need when a fixture has been removed or a box was never wired for a device. The box stays accessible for future use, just capped.
3) Can I use the Mulberry 40430 cover on a wall box instead of a ceiling box?
It's built for ceiling-mounted boxes, not wall boxes. Mulberry specifies the 40430 as a ceiling-mount cover for a proper fit and finished look overhead. For a wall-mounted 4-inch square box you want a wall-style blank square cover instead.
4) What is the Mulberry part number to order for a 4x4 blank ceiling cover?
Order Mulberry 40430. That's the manufacturer part number for the steel blank ceiling cover plate in the 4 x 4 inch size, and it is the only configuration of this cover.
5) What finish does the Mulberry 40430 ceiling cover come in, and can it be painted to match the ceiling?
Smooth enamel over steel. The smooth surface is snag-free and gives a uniform appearance that blends with surrounding trim and paint, which is why it's commonly used where the cover is visible overhead in a finished room.
6) Is the Mulberry 40430 cover durable enough for utility rooms, basements, and attics?
The 40430 is fabricated from steel rather than plastic, so it holds up to everyday impact in basement, attic, and utility room ceilings as well as finished residential and commercial spaces. Property managers capping boxes across a building get the same 4 x 4 inch footprint every time, which makes it easy to standardize.
