Mulberry 76403 Steel Princess Size 3-Gang GFI Block Wallplate, White
The Mulberry 76403 is a steel Princess Size 3-Gang GFI Block Wallplate finished in White, purpose-built to cover a 3-block combination of Duplex and GFI receptacles within a single multi-gang wall opening. Manufactured from steel, this wallplate offers the strength and rigidity needed for demanding residential, commercial, and light industrial applications where grouped receptacle devices are installed side by side. The Princess Size profile gives the plate a slim, streamlined outline that sits close to the wall surface, while the 3-gang GFI block layout is specifically dimensioned to accept a 3-block arrangement of Duplex/GFI receptacles without gaps or misalignment. Finished in White, the 76403 blends neatly with standard wall finishes, painted surfaces, and surrounding trim, making it a straightforward choice anywhere multiple duplex and ground-fault receptacles share a common wall box.
Key Features
- Steel Construction: Fabricated from steel for a rigid, impact-resistant cover plate that holds up to daily wear in busy residential and commercial spaces.
- 3-Gang GFI Block Configuration: Engineered to the 3-block Duplex/GFI receptacle layout, allowing three grouped devices to be covered by a single continuous plate.
- Princess Size Profile: Follows the Princess Size format, delivering a slim, low-profile fit that sits flush against the wall for a finished, professional look.
- White Finish: A clean White finish coordinates easily with common wall colors, devices, and trim throughout a room or facility.
- Combination Device Coverage: Purpose-sized for mixed Duplex/GFI receptacle groupings, eliminating the need to piece together multiple single-gang plates.
- Simplified Multi-Gang Installation: A single 3-gang plate covers the full device grouping in one piece, reducing installation time compared with separate single-gang covers.
- Consistent Wall Coverage: Uniform steel construction and Princess Size sizing help maintain a consistent look across multiple 3-gang GFI block locations in the same building.

Mulberry 76402 – Frequently Asked Questions
1) Will a Mulberry Princess GFI block plate cover a mix of duplex and GFCI receptacles in one box?
That is exactly what it is sized for. The GFI block layout is dimensioned for a grouped Duplex/GFI receptacle arrangement, so a single plate covers the whole run rather than piecing together separate single-gang covers. Pick the gang count to match the number of devices in the box: 2, 3, or 4.
2) Can a Leviton Decora wallplate be used in place of a Mulberry 76402 GFI block plate?
No. The Mulberry 76402 is a 2-gang steel plate with block-style Duplex/GFI cutouts. The Leviton 16252 is a Decora single-gang device wallplate and the Leviton 80601-T is a 1-gang Decora Midway plate, both single-gang with a decorator opening. They will not span a two-gang box and their opening shape does not match duplex or GFI receptacle faces. Use the Decora plates only where a single decorator-style device is installed.
3) What is the difference between the Mulberry 76404 steel GFI block wallplate and the Eaton 7729V-SP decorator triple-gang cover?
The Mulberry 76404 is a steel Princess Size 4-gang plate cut for a block arrangement of Duplex/GFI receptacles, finished in White. The Eaton 7729V-SP is a decorator triple-gang wallplate cover, so it carries three decorator-style rectangular openings rather than duplex/GFI block cutouts, and it covers three gangs rather than four. If the devices in the box are decorator rockers or decorator-style GFCIs, the openings match the Eaton; if they are duplex and GFI receptacles in a block layout, the Mulberry cutout is the one dimensioned for them.
4) Is this plate a standard size or an oversized cover?
It follows the Princess size format, which is a slim, low-profile outline that sits close to the wall rather than an oversized or jumbo plate. If your existing openings are rough and you need extra coverage around the device, a Princess size plate is the wrong choice.
5) Is the Mulberry 76403 metal or plastic?
Steel. That gives a rigid, impact-resistant cover for corridors, kitchens, laundry rooms, shops, and other high-traffic spots where a thermoplastic plate gets cracked. If you want plastic instead, the Cantex 5133330 is a PVC plate and the Eaton 3533-4W is white thermoplastic.
6) I'm covering just one GFCI outlet. Is the 2-gang 76402 the smallest option?
Within the 7640 Princess GFI block family, yes, 2-gang (76402) is the smallest. It is built to span two grouped devices, so it will not sit correctly over a single-gang box. For one device, use a single-gang plate such as the Leviton 80601-T.
7) I need a nonmetallic alternative to the Mulberry steel wallplates for a single switch - what is comparable?
For a single toggle switch opening, the Cantex 5133330 is a PVC single toggle switch wallplate, a nonmetallic plate with a toggle cutout. It covers one gang only, whereas the Mulberry 76402, 76403 and 76404 are steel plates covering two, three and four gangs of Duplex/GFI block devices. Choose the Cantex where a single switch is involved and a nonmetallic plate is wanted; the Mulberry plates remain the match for grouped receptacle boxes.
8) Will the Leviton 80601-T Midway plate give me more coverage around a receptacle than a Mulberry Princess plate?
They are different sizing conventions. The Leviton 80601-T is a 1-gang Decora Midway plate, midway being an intermediate size between standard and oversize for one device. The Mulberry 76402, 76403 and 76404 follow the Princess Size format, a slim low-profile outline that sits close to the wall, and are built for 2-, 3- and 4-gang Duplex/GFI block groupings. The Leviton is a single-device plate with a decorator opening, so it is not an option for a multi-gang receptacle box regardless of size.
9) What should I order instead of a Mulberry GFI block wallplate for a surface-mounted phone jack location?
The Mulberry 76403 covers a 3-block Duplex/GFI receptacle grouping and has no communications opening. For a telephone outlet, the Eaton 3533-4W is a surface mount telephone jack wallplate in white thermoplastic with RJ11/RJ14 termination. It is a jack assembly rather than a receptacle cover, so it serves the voice drop while the Mulberry plate handles the power devices.
10) What color are the Mulberry 7640 series wallplates?
White across all three gang sizes, which coordinates with standard white devices and painted wall trim. No other color is offered in this series, so if you are standardizing a facility on white receptacles it will match.
11) Are these Mulberry plates suitable for commercial and light industrial jobs, not just houses?
Yes. The steel construction is aimed at residential, commercial, and light industrial receptacle installations, including kitchen, bath, laundry, and utility GFI coverage, new construction, remodels, and maintenance replacements of damaged covers.
12) For a job where I am buying single-gang plates in bulk, is there an alternative to the Mulberry plates?
The Mulberry Princess Size plates are sold in 2-gang, 3-gang and 4-gang GFI block configurations for grouped devices. Where the openings are single-gang decorator devices, the Leviton 16252 is a Decora single-gang device wallplate supplied as a pack of 100, which suits repeat single-device locations across a building. It does not substitute for the Mulberry plates at any multi-gang box.
