Mulberry 30537 – Frequently Asked Questions

1) Will the Mulberry 30537 weatherproof cover fit a standard single-gang outdoor box?
Yes. The Mulberry 30537 is a 1-Gang cover sized for standard single-gang exterior boxes, receptacles and switches. It mounts in the vertical orientation, so the device inside needs to be oriented vertically as well. If your outlet sits horizontally in the box, you want a horizontal-mount cover instead.
2) What does self-closing mean on an outdoor outlet cover, and does it stay closed when something is plugged in?
Self-closing means the lid springs back over the device on its own the moment you let go, so nobody has to remember to shut it. On the Mulberry 30537 that keeps rain, dust and debris off the receptacle or switch between uses. It is a while-not-in-use design, not an in-use (bubble) cover, so it will not close over a cord that is left plugged in. If you need a cord connected full time in a wet location, you need an in-use cover instead.
3) What is the closest equivalent to the Mulberry 30537 weatherproof cover if I need a non-metallic version?
The Leviton 7788-CR is a 1-gang weatherproof self-closing cover made from glass-filled thermoplastic, so it covers the same single-gang self-closing function as the Mulberry 30537 without a metal body. The 30537 uses a die-cast aluminum body with a powder-coated finish, which is the difference that matters where impact or physical abuse is expected; the thermoplastic Leviton is the choice where a non-conductive, corrosion-immune cover is preferred, such as coastal or chemical exposure.
4) My outdoor box is mounted horizontally - is the Mulberry 30537 still the right cover?
The Mulberry 30537 is configured for vertical mount installation, so it is intended to match a device oriented vertically in a 1-gang box. For an opening where the device sits horizontally, the Leviton 7420 series and Leviton 7788-CR are 1-gang self-closing weatherproof covers that can be considered in place of it. Confirm the device orientation at the box before ordering, since the self-closing lid has to seat over the receptacle or switch the way it is installed.
5) For standardizing outdoor receptacle covers across a property, what are the practical differences between the Mulberry 30537 and the Leviton 7788-CR?
Both are 1-gang weatherproof self-closing covers, so either will give maintenance staff a lid that returns over the device on its own with no manual latch to remember. The Mulberry 30537 is die-cast aluminum with a powder-coated finish; the Leviton 7788-CR is glass-filled thermoplastic and is rated Industrial Grade. Fleets standardizing on a metal cover for high-traffic exteriors go with the 30537, while a property that wants a non-metallic cover with a stated grade on record standardizes on the 7788-CR.
6) Is the Mulberry 30537 the same thing as a flip-lid box cover or an in-use weatherproof cover?
No. The Mulberry 30537 is a 1-gang self-closing weatherproof cover, meaning the lid returns closed over the device when it is not in use - it is not designed to stay closed over a plugged-in cord. The Leviton 7420 series and Leviton 7788-CR are the same self-closing type of cover in glass-filled thermoplastic. If the receptacle will have a cord plugged in continuously, that calls for an in-use (extra-duty) enclosure rather than any of these three self-closing plate covers.
7) Can I use the Mulberry 30537 cover on a switch as well as a receptacle?
Yes. The 30537 is built to cover single-gang outdoor receptacles and switches alike, so it works for an exterior light switch by an entry or a garage as well as an outlet.
8) Will an aluminum weatherproof cover hold up outdoors without repainting?
The 30537 body is die cast aluminum with a powder-coated finish over it, which is what handles moisture, UV and general weathering. It is a low-maintenance cover, with no manual latch to work and no routine upkeep called for in normal exterior service.
9) What is the Mulberry part number for the 1-gang vertical self-closing weatherproof cover?
Order it as Mulberry 30537. That part number covers the die cast aluminum, powder-coated, 1-gang self-closing cover in the vertical mount orientation.
