Bell 5321-0 1-Gang Weatherproof Outlet Box, Aluminum

The Bell 5321-0 is a 1-Gang Weatherproof Outlet Box engineered from rugged aluminum with a gray finish, built to shield wiring devices from rain, dust, and outdoor exposure. This metallic-construction box features four 1/2 in. threaded outlets, giving installers multiple points of conduit entry from a single compact enclosure with a 2.148 in. depth. Backed by UL Listing and CSA Certification, the 5321-0 delivers the code-compliant protection required for exterior receptacles, switches, and other wiring devices exposed to the elements. Its aluminum body and weatherproof design make it a reliable choice for both new construction and retrofit outdoor electrical work.

Key Features

  • Four Threaded Outlets: Four 1/2 in. threaded outlets allow electricians to route multiple conduit runs into a single 1-gang enclosure, simplifying outdoor conduit layouts.
  • Aluminum Construction: Built from aluminum with metallic construction throughout, the 5321-0 resists corrosion and holds up to repeated outdoor exposure better than lightweight plastic alternatives.
  • Compact 2.148 in. Depth: The box's 2.148 in. depth keeps the enclosure low-profile, making it easier to mount flush against exterior walls and structures.
  • 1-Gang Sizing: Sized for a single wiring device, the 1-gang footprint keeps the installation compact while still supporting a full weatherproof seal.
  • Gray Finish: A neutral gray finish is designed to blend in with common outdoor conduit, fittings, and siding colors.
  • Metallic Housing: The metallic construction provides added mechanical durability compared to non-metallic weatherproof boxes in demanding job-site conditions.
  • Code-Compliant Protection: UL Listed and CSA Certified for use where outdoor electrical devices must meet recognized safety standards.

Bell 5321-0 – Frequently Asked Questions

1) Does the Bell 5321-0 weatherproof box come in 3/4 inch hub size as well as 1/2 inch?
Two trade sizes are offered on the Bell 1-gang aluminum weatherproof box. The 5321-0 has 1/2 inch threaded outlets; order the 5330-0 if your conduit runs are 3/4 inch. Match the hub size to the conduit you're landing, since the outlets are threaded and not knockouts.
2) How many conduit entries does the Bell 5321-0 outdoor box have, and can I feed through it?
Four threaded 1/2 inch outlets, so you can bring conduit in and out of the same 1-gang enclosure and use it as a pass-through or a multi-conduit junction point rather than a dead end. Unused hubs need plugging with threaded closure plugs to keep the enclosure weathertight.
3) How deep is the Bell 1-gang weatherproof box, and will a GFCI receptacle fit?
Depth is 2.148 inches. That's a standard single-gang weatherproof depth, and it's shallow enough to sit close to the wall on exterior siding or block. Check your device and conductor fill against that depth before you make up the splices, since a GFCI body plus several conduit entries takes up room.
4) Is the Bell 5321-0 metal or plastic, and will it corrode outdoors?
Aluminum, metallic construction, with a gray finish. Metal gives you mechanical durability a non-metallic box does not, and aluminum holds up to outdoor exposure. Because the housing is metallic, it's part of the equipment grounding path, so bond it properly at the threaded conduit connections.
5) Can I use this Bell box for a two-device outdoor installation?
No. It's a 1-gang box sized for a single wiring device, one receptacle or one switch. For two devices side by side you need a 2-gang weatherproof box; this one will not accept a duplex plus a switch.
6) Will the Bell 5321-0 work on a retrofit, or is it only for new construction?
Both. It's a surface-mounted threaded-hub box, so it works for new exterior circuits and for replacing a failed outdoor box on existing conduit, as long as the existing runs are 1/2 inch threaded (use the 5330-0 for 3/4 inch). It will not land nonmetallic cable directly; you need threaded conduit or a fitting into the hub.
