Mulberry 30528 1-Gang Weatherproof Self-Closing Vertical Cover, Die Cast Aluminum

The Mulberry 30528 is a 1-Gang weatherproof self-closing cover engineered from durable die cast aluminum with a protective powder coated finish. Purpose-built for vertical mount installations, this cover is designed to automatically close over the receptacle opening, helping shield outdoor electrical devices from rain, dust, and debris whenever the outlet is not in use. The rugged die cast aluminum body resists the dents and corrosion that lighter-duty covers cannot withstand, while the powder coated finish adds an extra barrier against sun, moisture, and everyday weathering. Electrical contractors and facility maintenance teams rely on covers like the Mulberry 30528 to keep exposed receptacles code-ready and protected between uses.

Key Features

  • 1-Gang Configuration: Sized to fit standard single-gang outdoor receptacle boxes and weatherproof enclosures.
  • Durable Die Cast Aluminum Construction: The die cast aluminum body delivers the strength, dent resistance, and long-term corrosion resistance needed for exposed outdoor electrical equipment.
  • Self-Closing Design: The cover automatically closes over the receptacle when not in use, helping keep rain, dust, and debris away from live connections.
  • Vertical Mount Orientation: Configured for vertical-mount receptacle applications, matching the orientation of the outlet it protects.
  • Powder Coated Finish: A powder coated exterior adds an additional layer of protection against sun exposure, moisture, and general weathering, helping the cover hold its appearance and function over time.
  • Weatherproof Protection: Combines the self-closing lid with a rugged aluminum housing to help protect outdoor receptacles from the elements between uses.

Mulberry 30528 – Frequently Asked Questions

1) Will the Mulberry 30528 weatherproof cover fit a single-gang outdoor receptacle box?
The 30528 is a 1-gang cover, sized for standard single-gang outdoor receptacle boxes and weatherproof enclosures. If the box on the wall is a two-gang, this is the wrong cover.
2) Does the Mulberry 30528 cover mount vertically or horizontally?
Vertical mount only. The 30528 is configured for vertical-mount receptacle applications, so the orientation has to match the outlet it covers. A horizontally oriented receptacle needs a horizontal-mount cover instead.
3) Can I leave a cord plugged in under the Mulberry 30528 cover?
No. The 30528 is a self-closing cover, meaning the lid returns closed over the receptacle when nothing is in use. It is not an in-use (extra duty) enclosure. If a cord stays plugged in, like a block heater, pump, or holiday lighting, you want an in-use cover such as the TayMac MX4380S Extra Duty cover instead.
4) What is the closest equivalent to the Mulberry 30528 self-closing weatherproof cover?
The Leviton 7788-CR is the nearest match in function: a 1-gang weatherproof self-closing cover like the Mulberry 30528. The difference is the body material. The Mulberry 30528 is die cast aluminum with a powder coated finish, while the Leviton 7788-CR is glass-filled thermoplastic and is an industrial grade cover. Both are single-gang self-closing lids for an outdoor receptacle, so an electrician replacing a cover on an existing single-gang weatherproof box can use either; choose the aluminum body where the cover is exposed to impact and the thermoplastic where a non-metallic cover is preferred.
5) Is there a non-metallic alternative to the Mulberry 30528 for a coastal or corrosive outdoor location?
Yes. The Leviton 7420-YL is a 1-gang industrial grade self-closing weatherproof cover made of glass-filled thermoplastic, so there is no metal surface to oxidize at all. The Mulberry 30528 takes the opposite approach to the same problem, using a die cast aluminum body with a powder coated finish as its barrier against moisture and sun. For salt-air exposure where a maintenance team does not want to monitor a coating, the thermoplastic Leviton is the non-metallic route; where the cover may be struck by carts, mowers, or ladders, the aluminum body is the sturdier shell.
6) The cord has to stay plugged in with the lid shut. Is the Mulberry 30528 the right cover?
No. The Mulberry 30528 is a self-closing cover, designed to close over the receptacle when it is not in use, which means it is intended for intermittent use rather than a permanently connected cord. For a load that stays plugged in, use an in-use cover such as the TayMac MX4380S, a 1-gang weatherproof in-use cover in the Extra Duty Series, aluminum with a gray finish. The deeper in-use enclosure allows the lid to remain closed over a plug and cord, which is what inspectors look for on an outdoor receptacle serving equipment left connected.
7) Is the Mulberry 30528 metal or plastic?
Die cast aluminum, with a powder coated exterior. That is the difference from thermoplastic covers like the Leviton 7788-CR, which is glass-filled thermoplastic. Metal handles impact and abuse on exposed walls; thermoplastic avoids metal corrosion concerns in salt or chemical environments.
8) I need a weatherproof cover for a decorator-style GFCI outlet outside. Is the Mulberry 30528 the one?
The 30528 is described as a 1-gang vertical self-closing cover, not specifically as a decorator opening. For a decorator (rectangular) device opening in vertical orientation, the Bell Outdoor Comforts 1-gang vertical decorator weatherproof cover is the one built around that opening shape.
9) What is the difference between the Mulberry 30528 and the Bell 5123 vertical cover?
Both are 1-gang vertical weatherproof covers for an outdoor receptacle. The Bell 5123 is an Outdoor Comforts Series decorator cover, so its opening is cut for a decorator or GFCI style device face. The Mulberry 30528 is a self-closing cover built from die cast aluminum with a powder coated finish, with a lid that returns to the closed position once the outlet is no longer in use. Match the cover to the device already in the box: a decorator or GFCI face calls for the Bell, while the Mulberry suits a receptacle you want shielded automatically between uses.
10) If I want to standardize outdoor receptacle covers in aluminum across a property, what are the options?
Two aluminum-bodied covers serve different duty cases. The Mulberry 30528 is a 1-gang die cast aluminum self-closing vertical cover with a powder coated finish, for receptacles that sit idle most of the time and should be shielded automatically. The TayMac MX4380S is a 1-gang aluminum in-use cover in the Extra Duty Series, gray, for locations where a cord stays connected. A property manager can specify the 30528 at general-purpose exterior outlets and the MX4380S at outlets feeding pumps, lighting, or seasonal equipment, keeping both in the same metal family.
11) Will the Mulberry 30528 hold up on a coastal or high-sun exterior wall?
The body is die cast aluminum, which resists dents and corrosion better than lighter-duty covers, and the powder coated finish adds a barrier against sun, moisture, and general weathering. That combination is what property managers and electrical contractors use it for on exterior wall-mounted receptacle boxes.
12) What part number do I order for the Mulberry 1-gang vertical self-closing aluminum cover?
Order Mulberry 30528. That is the manufacturer part number for the 1-gang vertical self-closing weatherproof cover in die cast aluminum with a powder coated finish, and it is the single configuration offered.
13) Will the Leviton 7420-YL work as a drop-in for the Mulberry 30528 on a vertical outlet?
They are both 1-gang self-closing weatherproof covers, but confirm orientation before ordering. The Mulberry 30528 is configured specifically for vertical-mount receptacle applications, matching the orientation of the outlet it protects. The Leviton 7420-YL is an industrial grade self-closing cover in glass-filled thermoplastic. Verify the Leviton cover's device opening orientation matches the receptacle in the box, since a cover cut for the opposite orientation will not seat over the device face even on the same single-gang box pattern.
