Mulberry 30550 1-Gang Weatherproof Self-Closing Rectangular Cover, Die Cast Zinc

The Mulberry 30550 is a 1-Gang Weatherproof Self-Closing Rectangular Cover engineered for exterior electrical installations that demand durable, dependable device protection. Constructed from die cast zinc and finished with a powder-coated surface, this cover resists corrosion and holds up to repeated outdoor exposure. Its self-closing rectangular design automatically returns the lid to a closed position after use, helping keep moisture, dust, and debris away from the receptacle or switch mounted behind it. The compact 1-gang footprint makes it a straightforward upgrade or replacement for existing weatherproof device boxes on patios, porches, garages, entryways, and other exterior locations where a reliable, code-conscious cover is needed.

Key Features

  • Gang Configuration: 1-Gang design sized for a single exterior device opening.
  • Durable Construction: Die cast zinc body resists impact, warping, and corrosion in outdoor environments.
  • Self-Closing Operation: Spring-loaded, self-closing lid automatically returns to the closed position, protecting the device whenever it is not actively in use.
  • Weatherproof Design: Weatherproof construction helps keep rain, moisture, and debris out of the device box and wiring behind it.
  • Rectangular Cover Shape: Rectangular profile fits standard rectangular weatherproof device boxes for a clean, flush appearance.
  • Powder-Coated Finish: Powder-coated surface adds an extra layer of corrosion resistance while giving the cover a smooth, uniform appearance that holds up outdoors.

Mulberry 30550 – Frequently Asked Questions

1) Will the Mulberry 30550 cover fit a standard single-gang outdoor box?
The Mulberry 30550 is a 1-gang cover with a rectangular profile, so it mounts to standard rectangular weatherproof device boxes sized for a single exterior device opening. It's a direct swap for an existing 1-gang weatherproof cover on a patio, porch, garage, or entryway box.
2) Can I leave a cord plugged in with the Mulberry 30550 self-closing cover?
No. A self-closing cover like the 30550 has a spring-loaded lid that returns to closed when nothing is in use, so it protects the device between uses but does not close over a cord that stays plugged in. For a receptacle feeding a holiday light string, pump, or anything left connected outdoors, you want an in-use (bubble) cover instead.
3) My spec calls for an industrial grade weatherproof cover. Which options meet that?
The Leviton 7420 and the Leviton 7788-CR are both stated as industrial grade, 1-gang self-closing weatherproof covers in glass-filled thermoplastic, so either answers a drawing that calls out industrial grade by name. The Mulberry 30550 is specified on its construction instead: a die-cast zinc, powder-coated 1-gang self-closing weatherproof cover for wet and damp location device protection. If the submittal requires the words industrial grade, go with the Leviton parts; if it requires a metal cover, go with the 30550.
4) Should I use a metal or a thermoplastic self-closing cover on an outdoor receptacle?
Both are offered in 1-gang self-closing form. The Mulberry 30550 uses a die-cast zinc body with a powder-coated surface, which gives a metal cover that resists impact and corrosion outdoors. The Leviton 7420 and Leviton 7788-CR are glass-filled thermoplastic industrial grade covers, which is the non-metallic path for locations where a plastic cover is preferred or where metal is being avoided. Facilities standardizing across many exterior devices often pick one material family and stay with it so replacement covers always match what is already on the walls.
5) Is the Mulberry 30550 a metal cover or plastic?
Metal. The 30550 body is die cast zinc with a powder-coated finish over it. That combination is what handles impact and corrosion on exterior walls, and it's the main difference from the thermoplastic self-closing covers on the market.
6) Is there a non-metallic alternative to the Mulberry 30550 for a coastal or wash-down location?
Yes. The Leviton 7788-CR is a 1-gang self-closing weatherproof cover in glass-filled thermoplastic, and Leviton's 7420 is a glass-filled thermoplastic 1-gang industrial grade self-closing cover. Both give you the same self-closing function without a metal body, which some specs call for near salt air or where a metal plate isn't wanted.
7) Is the Leviton 7420 the same thing as the Leviton 7788-CR?
They are close but not identical. Both are 1-gang self-closing weatherproof covers built from glass-filled thermoplastic and both are industrial grade. The 7788-CR is catalogued with the CR suffix as a specific finish variant, so if you are matching an existing bank of covers, order by the full part number rather than treating the two as interchangeable. Neither is a metal cover; for that, the Mulberry 30550 is the die-cast zinc option.
8) If I need to cover two devices outdoors, will the Mulberry 30550 work?
No. The Mulberry 30550 is a 1-gang cover sized for a single exterior device opening, and the comparable self-closing covers from Leviton, the 7420 and the 7788-CR, are 1-gang as well. For a two-device exterior opening you need a 2-gang weatherproof cover rather than any of these three.
9) Can the Mulberry 30550 cover be used over an outdoor switch as well as a receptacle?
Yes. The 30550 is a device cover, and the self-closing lid protects whatever device sits behind it, receptacle or switch, on exterior residential and commercial wiring. Typical uses are entryway and walkway lighting switch legs and patio or garage receptacles.
10) What part number do I order for the Mulberry weatherproof self-closing rectangular cover?
Order Mulberry 30550. That's the manufacturer part number for the 1-gang die cast zinc self-closing rectangular weatherproof cover, and it ships as a single model with no finish or size options to specify.
