Mulberry 30451 1-Gang Weatherproof Self-Closing Rectangular Device Cover, Powder-Coated Die-Cast Zinc

The Mulberry 1-Gang Weatherproof Self-Closing Rectangular Cover is a powder-coated die-cast zinc device cover built to protect single-gang outdoor receptacles, switches, and other wiring devices from rain, dust, and everyday exposure. Its self-closing hinge automatically returns the cover to the closed position whenever the connected device is not in use, so the opening stays shielded without requiring the installer or end user to remember to close it manually. The rugged die-cast zinc body and rectangular cover profile are designed to hold up to repeated outdoor use, making this cover a practical choice for exterior receptacle and switch locations on homes, businesses, and job sites where dependable weatherproof coverage matters.

Key Features

  • 1-Gang Configuration: Sized to fit standard single-gang outdoor device boxes and weatherproof enclosures for a clean, secure fit.
  • Durable Die-Cast Zinc Construction: The rugged die-cast zinc body delivers long-term strength and resistance to the wear and tear of outdoor conditions.
  • Self-Closing Hinge Design: A spring-assisted hinge automatically returns the cover to the closed position when not in use, helping keep the device shielded from moisture and debris even during everyday use.
  • Powder-Coated Finish: The powder-coated exterior resists corrosion, chipping, and fading, helping the cover keep its appearance and function through repeated outdoor exposure.
  • Weatherproof Protection: The rectangular cover profile is built to shield connected receptacles and switches from rain and general outdoor exposure.
  • Rectangular Cover Profile: A common rectangular footprint that is compatible with standard outdoor single-gang device box openings.

Mulberry 30451W – Frequently Asked Questions

1) Will the Mulberry 30451 weatherproof cover fit a standard single-gang outdoor box?
Yes. The Mulberry 30451 is a 1-gang cover with a rectangular profile sized for standard single-gang outdoor device boxes and weatherproof enclosures, so it drops onto the common exterior box openings used for receptacles and switches.
2) Is a self-closing cover like this OK for an outdoor receptacle that has something plugged in all the time?
No, not for a permanently plugged-in load. A self-closing cover springs shut when the device is not in use, which protects an idle receptacle but does not enclose a cord while it is connected. For a receptacle in constant use outdoors you want an in-use (extra duty) cover such as the TayMac MX4380S 1-Gang Weatherproof In-Use Cover from the Extra Duty Series, which closes over the plug and cord.
3) Is the Bell 5123-0 a direct replacement for a Mulberry 30451 cover?
Not in every opening. Both are 1-gang weatherproof covers, but the Bell 5123-0 is an Outdoor Comforts series vertical decorator cover in gray, so its opening is cut for a decorator/rocker style device mounted vertically. The Mulberry 30451 is a rectangular device cover with a self-closing hinge, powder-coated die-cast zinc. If the device behind the plate is a decorator rocker or GFCI face, the Bell opening matches it; if you are covering a standard rectangular device opening and want the lid to return closed on its own, the 30451 is the matching form.
4) What should I use instead of the Mulberry 30451 self-closing cover if a cord stays plugged in all the time?
The Mulberry 30451 is a 1-gang self-closing cover: the spring-assisted hinge returns the lid to the closed position when the device is not in use, which suits receptacles and switches that are only used intermittently. For an outdoor receptacle that keeps a cord connected continuously, an in-use (while-in-use) cover is the right form, such as the TayMac MX4380S 1-gang weatherproof in-use cover from the Extra Duty series, an aluminum cover in gray. The in-use style encloses the plug body itself with the lid latched down over the cord, while the self-closing lid of the 30451 is designed to shut against the device face.
5) Does a self-closing cover work for a damp location switch on a patio wall?
That's exactly what it's for. The spring-assisted hinge returns the cover to closed whenever the switch or receptacle is not being used, so the opening stays shielded from rain and debris without anyone remembering to shut it. Typical spots are patio, deck and exterior wall installations on both residential and commercial buildings.
6) Do I need to buy a box or gasket separately with the Mulberry 30451 cover?
The 30451 is the cover only. It mounts to a single-gang outdoor device box or weatherproof enclosure, which you supply along with the wiring device itself. Plan the box, the device, and any gasket or sealant your installation calls for as separate line items.
7) For exterior receptacles on a commercial building, how does the Mulberry 30451 differ in material from the comparable aluminum covers?
The Mulberry 30451 uses a powder-coated die-cast zinc body, with the powder coating resisting corrosion, chipping, and fading through repeated outdoor exposure; a die-cast aluminum version is also offered under part number 30451W. The TayMac MX4380S, by comparison, is an aluminum cover in gray. Zinc die-cast bodies are heavier for a given size, while aluminum reduces weight; both are used on exterior wall receptacle and switch locations.
8) I need a weatherproof cover for a single outdoor switch that nobody remembers to close. Which option handles that?
The Mulberry 30451 1-gang rectangular cover is the one built for that problem: its spring-assisted hinge returns the lid to the closed position automatically whenever the device is not in use, so the opening stays shielded from rain and debris without anyone closing it by hand. The comparable 1-gang covers take different approaches - the TayMac MX4380S is an in-use cover, meant to stay latched over a connected cord, and the Bell 5123-0 is a vertical decorator cover. For an intermittently used exterior switch or receptacle, the self-closing 30451 is the form that matches the behavior you described.
9) Can I standardize this same cover across a whole property's exterior receptacles?
Yes, and that's a common use for it. One 1-gang rectangular self-closing cover suits exterior receptacle and switch locations across homes, businesses and job sites, in both renovation and new construction, so a property manager can spec the same part number for every single-gang exterior opening. Just separate out any receptacle that stays plugged in continuously, since those need an in-use cover instead.
