Thomas & Betts Red-Dot 2IH3-2 2-Gang RT Box, Three 3/4" Hubs

The Thomas & Betts Red-Dot 2IH3-2 is a 2-Gang RT box built with three 3/4" threaded hubs for conduit entry and termination. Part of the Red-Dot product line from Thomas & Betts, this RT-style enclosure gives electricians a single, compact body for two-gang device and wiring installations where multiple conduit runs converge at one location. The three 3/4" hub openings allow conduit to be routed into the box from multiple directions, simplifying layout on jobs where more than one circuit or raceway terminates at a single device point. This 2-gang, three-hub configuration makes the 2IH3-2 well suited for multi-conduit Red-Dot installations on commercial and industrial projects.

Key Features

  • Trade Size: Equipped with three 3/4" hubs, providing dedicated conduit entry points into the box.
  • 2-Gang Configuration: Sized to accommodate two-gang device and wiring installations within a single enclosure.
  • RT Box Design: Built to the Red-Dot RT box style for dedicated conduit routing and termination applications.
  • Threaded Hub Connections: Three separate 3/4" threaded hubs support flexible conduit routing into the box from multiple directions.
  • Single-Point Termination: Consolidates three 3/4" conduit entries and a 2-gang device space into one compact box body.
  • Compact Enclosure: Combines gang space and hub entries in one body, reducing the need for separate junction points.
  • Red-Dot Product Line: Manufactured under the Red-Dot brand of Thomas & Betts for conduit-based electrical installations.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Electrical Device and Junction Box Installations
  • Two-Gang Device Wiring Applications

Thomas & Betts TB2IH3-2 – Frequently Asked Questions

1) How many conduit entries does the Red-Dot 2IH3-2 box have, and what size are they?
The Red-Dot 2IH3-2 has three hubs, all 3/4 inch, threaded. Because they enter from more than one direction, you can land multiple conduit runs at one box instead of adding a separate junction point upstream. All three are the same trade size, so there is no mixed-size hub to plan around.
2) Will the 2IH3-2 take two devices, like a switch and a receptacle?
Yes. It is a 2-gang box, so it is sized for two-gang device and wiring installations in a single body. A switch and receptacle side by side, or two receptacles, is the intended use.
3) Do I need conduit connectors, or does the 2IH3-2 thread straight onto the raceway?
The hubs are threaded, so 3/4 inch threaded conduit or a threaded fitting screws directly into the box. No box connector or locknut-and-bushing entry is needed on those three openings, which is the point of an RT-style hub box versus a knockout box.
4) Is the Cantex EZ20SB EZ Box a substitute for the Thomas & Betts Red-Dot 2IH3-2?
No. The Red-Dot 2IH3-2 is a 2-gang box with threaded 3/4 inch hub connections for conduit entry, while the Cantex EZ20SB is a 1-gang non-metallic steel stud box. The EZ20SB is a single-device enclosure mounted to steel studs rather than a threaded conduit-terminated body, so it neither matches the 2-gang device space nor accepts threaded conduit at hubs. Use the 2IH3-2 where conduit runs must thread directly into a two-gang box.
5) Is the Thomas & Betts 2IH3-2 sold individually or by the case?
It ships as a pack of 100. That is a contractor or distributor quantity, so if you only need a handful of boxes for one opening, a bulk case is more than the job calls for.
6) Should I use a hub box like the 2IH3-2 or a standard square box for a conduit run?
Use the 2IH3-2 where rigid or threaded conduit terminates and you want the raceway landed directly on the box, with three 3/4 inch entries at one point. Where you are pulling into a stud wall or working with a flush-mounted device ring instead, a knockout-style box is the fit, such as the RACO 232MS 4 in. square welded box in the STAB-iT Series, or the Cantex EZ20SB EZ Box 1-gang non-metallic steel stud box for single-gang stud framing.
7) I only need a single-device box on a steel stud wall - do I still need the 2IH3-2?
No. For a single device in a steel stud partition, the Cantex EZ20SB EZ Box is a 1-gang non-metallic steel stud box. The Thomas & Betts Red-Dot 2IH3-2 is sized for two-gang device and wiring installations and uses threaded 3/4 inch hubs for conduit, which is more enclosure and more conduit provision than a single-gang stud-mounted device needs.
8) What should I use instead of the Red-Dot 2IH3-2 if I need a deep square box for splicing rather than a hubbed two-gang body?
Consider the RACO 232MS, a 4 inch square welded box in the STAB-iT series, 2-1/8 inches deep and rated 600V. It gives you a square welded body with depth for conductor splicing, whereas the Thomas & Betts Red-Dot 2IH3-2 is a 2-gang box with three 3/4 inch threaded hubs intended to terminate multiple conduit runs at a single device location.
9) Can the RACO 232MS square box replace a Red-Dot 2IH3-2 where three 3/4 inch conduits land?
Not directly. The Red-Dot 2IH3-2 has three factory 3/4 inch threaded hubs, so conduit threads straight into the box body with no separate connectors. The RACO 232MS is a 4 in. square welded box, 2-1/8 in. deep, and is not a hubbed enclosure, so conduit entries would be made through knockouts with fittings. Where the design calls for threaded hub entry at a 2-gang device point, the 2IH3-2 is the matching part.
10) I only have two conduit runs coming into the box. Can I still use the 2IH3-2?
Yes, though all three 3/4 inch hubs are threaded openings that will need to be closed off if unused. If you know you will only ever land two runs, a two-hub Red-Dot body keeps you from having to plug one. Where the third run may be added later, the spare hub is the reason to buy this one.
11) For standardizing boxes across a building, how do the 2IH3-2, EZ20SB, and 232MS differ in what they cover?
They cover three different roles. The Thomas & Betts Red-Dot 2IH3-2 is the 2-gang, threaded-hub body for 3/4 inch conduit terminating at a device point, supplied 100 per pack. The Cantex EZ20SB is a 1-gang non-metallic box for steel stud framing. The RACO 232MS is a 4 in. square welded box, 2-1/8 in. deep, rated 600V, for square-box device and splice work. Facilities running rigid conduit standardize on the hubbed 2IH3-2 at two-gang locations.
