Orbit 2B75-5 2-Gang Weatherproof Outlet Box, Die-Cast Aluminum

The Orbit 2B75-5 is a 2-gang weatherproof outlet box built from powder-coated, copper-free die-cast aluminum, engineered for durable exterior and industrial device mounting applications. This box measures 4-9/16" x 4-1/2" x 2" deep, with an interior volume of 30.5 cubic inches, and features 5 outlet holes sized for 3/4" device mount hardware. Finished in gray, the 2B75-5 is designed to house switches, receptacles, and other wiring devices while standing up to outdoor exposure and corrosive environments. Its copper-free aluminum construction resists galvanic corrosion, making it a reliable choice wherever standard steel or copper-alloy boxes would be at risk.

Orbit 2B75-5 – Frequently Asked Questions

1) How much wiring volume does the Orbit 2B75-5 2-gang box give me for box fill calculations?
Interior volume is 30.5 cubic inches across the 2-gang body, which is 2 inches deep. That is the number to use when you run your conductor and device fill count.
2) Will a standard weatherproof cover and gasket fit the Orbit 2B75-5?
The box measures 4-9/16 x 4-1/2 x 2 inches, a footprint made to take standard 2-gang weatherproof cover and gasket assemblies. The covers and gaskets are separate items, so order the cover style that matches the devices going in (duplex receptacle, toggle switch, or blank).
3) What is the closest equivalent to the Orbit 2B75-5 if I need three devices in one weatherproof box instead of two?
Step up to the Mulberry 30601 Royal Mountie, a powdered die-cast aluminum 3-gang weatherproof outlet box. It shares the Orbit 2B75-5's die-cast aluminum weatherproof construction but houses three wiring devices rather than the two the 2B75-5 is configured for, so it is the one to specify when a single exterior opening has to carry a third switch or receptacle. Plan cover and gasket selection around the 3-gang footprint, not the 2-gang.
4) Is the Thomas and Betts Red-Dot 2IH3-1 a drop-in replacement for an Orbit 2B75-5?
Not a drop-in. Both are 2-gang boxes, but the Red-Dot 2IH3-1 is a conduit outlet box with three 1/2 inch hubs cast into the body, while the Orbit 2B75-5 has 5 pre-formed outlet holes sized for 3/4 inch device mount hardware and an interior volume of 30.5 cubic inches in a 4-9/16 x 4-1/2 x 2 inch body. If the runs coming into the opening are 3/4 inch, the 2B75-5 matches them without adapters; if they are 1/2 inch conduit, the 2IH3-1 hubs land directly. The 2IH3-1 is also sold as a pack of 100, which suits standardizing a large exterior rough-in rather than a single device swap.
5) Is a die-cast aluminum outlet box safe to use in coastal or salt-air locations?
Yes. The 2B75-5 body is copper-free die-cast aluminum, which is specified exactly to avoid galvanic reaction, and it carries a powder-coated gray finish over that for weather and UV exposure. Copper-free alloy is the standard call for coastal, marine, and chemically corrosive exterior work where a steel box would rust out.
6) Is the Orbit 2B75-5 a conduit outlet box with threaded hubs or a device box?
It is a 2-gang device box with five 3/4 inch device mount outlet holes, intended to house receptacles, switches, and other wiring devices outdoors. If you want factory threaded hubs instead of outlet holes, the Thomas and Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs.
7) Should I use a PVC multi-gang box or an aluminum one for an outdoor receptacle?
Aluminum, like the Orbit 2B75-5, is the usual choice for commercial and industrial exterior device mounting where the box takes physical abuse, and the copper-free alloy handles corrosive air. A nonmetallic option like the Cantex EZ Series PVC multi-gang box is a residential box and is nonconductive, so it needs no bonding of the enclosure itself. Pick aluminum for exposed commercial work, PVC where you are already running PVC raceway on a house.
8) Is the Orbit 2B75-5 weatherproof on its own once the devices are in?
Not by itself. The casting shields the devices from moisture only when it is paired with the matching weatherproof cover and gasket, which are ordered separately. Budget for the cover, the gasket, and fittings for the 3/4 inch openings to finish the install.
9) Can I use a Cantex EZ Box instead of the Orbit 2B75-5 on an exterior wall?
They are built for different jobs. The Cantex EZ Series is a PVC multi-gang residential outlet box, while the Orbit 2B75-5 is a copper-free die-cast aluminum weatherproof box with a powder-coated gray finish, intended for outdoor and industrial device mounting and corrosion-prone or coastal environments. For a residential multi-gang interior rough-in the EZ Box covers it; for an exposed exterior receptacle or switch where galvanic corrosion and UV are in play, the 2B75-5 aluminum body with a weatherproof cover and gasket is the correct specification.
10) For a coastal property where boxes keep corroding, does the Orbit 2B75-5 or the Mulberry 30601 hold up better?
Both are die-cast aluminum weatherproof boxes, so neither is the steel or copper-alloy body that fails first in salt air. The Orbit 2B75-5 specifies copper-free die-cast aluminum to resist galvanic reaction, with a powder-coated gray finish added over it for weathering and UV; the Mulberry 30601 Royal Mountie is a powdered die cast aluminum body. Choose between them on gang count rather than material: the 2B75-5 for two devices, the 30601 for three.
11) What is the Orbit part number and finish color for this 2-gang weatherproof box?
Order it as Orbit 2B75-5. It ships in a gray powder-coated finish, which matches the standard gray of most weatherproof covers so a multi-box exterior run looks uniform.
