Mulberry 30316 Die-Cast Aluminum Weatherproof Box, 4-Inch x 1-1/2-Inch

The Mulberry 30316 Weatherproof Box is a die-cast aluminum electrical box engineered for outdoor and wet-location wiring connections that demand rugged, long-term protection. Measuring 4-Inch x 1-1/2-Inch with a 15.3 cubic-inch interior capacity, this compact box provides ample room for splices, device connections, and junction work while maintaining a low-profile footprint that fits neatly against exterior walls, soffits, and equipment enclosures. The powder-coated die-cast aluminum housing resists corrosion, impact, and constant exposure to the elements, making the 30316 a dependable choice for electricians working on exterior lighting, receptacles, switches, and junction points where a standard indoor box will not hold up. This weatherproof box is available in Bronze, Gray, and White finishes to match a range of exterior color schemes.

Key Features

  • Trade Size: Measures 4-Inch x 1-1/2-Inch, sized for tight outdoor and exterior wall installations where space around the box is limited.
  • Durable Construction: Die-cast aluminum housing delivers rugged strength and long-term corrosion resistance for repeated outdoor exposure and rough handling on the jobsite.
  • Generous Capacity: 15.3 cubic inches of interior volume accommodates wire splices, device connections, and grounding conductors with room to spare for clean terminations.
  • Finish: Powder-coated finish adds an extra layer of durability against moisture, UV exposure, and general wear over years of outdoor service, available in Bronze, Gray, or White.
  • Weatherproof Design: Built to help protect wiring connections in outdoor and wet-location electrical environments from rain, humidity, and temperature swings.
  • Aluminum Housing: Lightweight yet rigid die-cast aluminum body simplifies handling and mounting compared to bulkier enclosure materials.

Mulberry 30316Z – Frequently Asked Questions

1) How much wire fill does the Mulberry 30316 weatherproof box give me?
The 30316 holds 15.3 cubic inches inside a 4-inch by 1-1/2-inch body. That is enough room for splices, device terminations, and grounding conductors without forcing the wires when you set the cover. Count your conductors against that 15.3 cu-in figure the way you would on any box, then pick your device or blank cover.
2) Can the Mulberry 30316 aluminum box be used outdoors in a wet location?
That is what it is built for. The die-cast aluminum body carries a powder-coated finish to resist corrosion and UV, and the box is intended for outdoor and wet-location wiring, exterior lighting, receptacles, switches, and junction points where an indoor box will not survive. Weatherproof performance still depends on pairing it with the proper gasketed cover and sealing the conduit entries.
3) What is the closest two-gang alternative to the Mulberry 30316 weatherproof box?
The Mulberry 30316 is a single 4-inch x 1-1/2-inch die-cast aluminum weatherproof box with 15.3 cubic inches of interior volume, sized for one device or a small splice. When the opening needs two devices side by side, the Pass & Seymour WPB series weatherproof two-gang box is the die-cast aluminum counterpart, built for the same outdoor wet-location duty in a two-gang footprint. Both are die-cast aluminum, so conduit runs and mounting practice carry over; the difference is gang count and the overall box outline.
4) I need more wire room than 15.3 cubic inches in a single-gang outdoor box - what should I use instead?
The Mulberry 30316 is a 1-1/2-inch deep box with 15.3 cubic inches of capacity, which fills up quickly once you add a device, several splices and grounds. For a single-gang outdoor location that needs more room, the Pass & Seymour WPBD series is a weatherproof one-gang deep box, gaining its volume through added depth rather than a wider footprint. Choose on how far the box can stand off the wall: the 30316 keeps a low profile against siding and soffits, the deep box trades that profile for interior space.
5) What colors does the Mulberry 30316 weatherproof box come in, and do I have to change the part number?
Three colors, and yes, the number changes. Gray is the base 30316, white is 30316W, and bronze is 30316Z. Property managers standardizing across a building usually pick bronze for dark trim or fixtures and white for light stucco or siding, so the box disappears against the wall instead of needing field paint.
6) Why choose a die-cast aluminum weatherproof box over a plastic or nonmetallic outdoor box?
Aluminum takes impact and rough handling that a nonmetallic box will not, and it stays rigid on an exposed wall, soffit, or equipment enclosure. It is also lighter than heavier cast enclosures, which matters when you are mounting overhead. The trade-off: a metallic box is part of the grounding path, so you bond it, and it needs the powder-coat intact to hold off corrosion in coastal or chemical environments.
7) Does the Mulberry 30316 weatherproof box include a cover?
The 30316 is the box itself, a weatherproof enclosure in die-cast aluminum. Plan on ordering the cover separately and matching it to the job: a blank cover for a junction point, a device or receptacle cover for a switch or outlet, and a gasket so the assembly stays sealed. Match the cover color to the box you order (gray, white, or bronze) if appearance matters.
8) Will the Mulberry 30316 work as a conduit junction point on an exterior wall?
Yes. Exterior conduit and raceway connection points are one of its listed uses, along with equipment and fixture mounting on outdoor surfaces. The shallow 1-1/2-inch depth keeps it tight to the wall, and the 15.3 cubic inches gives you space for pull-through and splices. Confirm the hub sizes on the specific box match your conduit before you rough in.
9) Does the Pass & Seymour WPBD deep box come in bronze or white to match an exterior?
The Mulberry 30316 is offered in gray, white and bronze powder-coated finishes, so it can be matched to siding, trim or a bronze light fixture without painting. The Pass & Seymour WPBD one gang deep box is a gray box. If finish match across a building's exterior devices matters to the property owner, the 30316 is the one that gives you the color choice; if depth is the driver, plan on the gray.
10) Can I use a Pass & Seymour WPB two-gang box where a Mulberry 30316 was removed?
Not as a direct swap. The Mulberry 30316 is a single-gang 4-inch x 1-1/2-inch die-cast aluminum box, and the Pass & Seymour WPB series box is a two-gang enclosure, so the wall penetration, cover and device plate all change. Replace a 30316 with another single-gang weatherproof box unless you are deliberately converting the opening to two devices, in which case the two-gang box and its matching two-gang weatherproof cover are what the job calls for.
