Topaz Lighting 981S Steel Rigid Male Enlarger, 1/2" to 3/4"

The Topaz Lighting 981S Steel Rigid Male Enlarger is a 1/2" to 3/4" transition fitting built for rigid metal conduit (RMC) raceway systems. Constructed from durable steel with a threaded male design, it lets electricians step up from a 1/2" conduit run to a 3/4" conduit run without breaking raceway continuity. This male enlarger is an essential adapter for electricians and contractors who need to change trade sizes mid-run while keeping the conduit system mechanically sound and electrically continuous. It is a straightforward, code-compliant solution for adapting trade sizes in commercial and industrial installations, panelboards, and junction box entries.

Key Features

  • Trade Size: 1/2" to 3/4" transition, enabling a step-up connection between two rigid conduit trade sizes without additional couplings.
  • Durable Construction: Made from steel for strength and long-lasting performance in demanding electrical installations, indoors or in protected outdoor locations.
  • Type: Rigid Male Enlarger fitting, designed to enlarge from a smaller to a larger conduit trade size within a threaded rigid conduit system.
  • Compatibility: Suitable for use with rigid metal conduit (RMC) systems requiring a 1/2" to 3/4" size transition at panels, boxes, or fittings.
  • Reliable Connection: Threaded male design ensures a secure, stable fit within the conduit raceway, maintaining system continuity and mechanical protection for conductors.
  • Space-Saving Adaptation: Eliminates the need for separate reducing bushings or couplings when stepping up conduit trade size at a single fitting.

Technical Specifications

  • Product Type: Conduit Bodies & Fittings
  • Conduit Type: Rigid/IMC

Topaz Lighting 981S – Frequently Asked Questions

1) What does the Topaz 981S male enlarger actually do in a conduit run?
The 981S steps a 1/2 inch rigid conduit connection up to 3/4 inch at a single fitting. The male end threads into the 1/2 inch side and the larger end accepts the 3/4 inch conduit or fitting, so you get the size change without stacking a coupling and a bushing together.
2) Will the 981S enlarger work with IMC, or is it rigid only?
It is listed for Rigid/IMC. Both RMC and IMC use the same threaded trade-size connections, so the 981S threads to either. It will not work on EMT, which is a set-screw or compression system with no threads.
3) I need to go from 3/4 inch down to 1/2 inch - can I use the 981S backwards?
No. The 981S is a male enlarger, meaning it goes small to large: 1/2 inch up to 3/4 inch. For the opposite direction you want a reducer or a reducing bushing, not this fitting. Check the direction of your run before ordering, because the male thread is on the small side.
4) Do I get one enlarger or a box when I order the Topaz 981S?
It's packed 100 to a unit. That's a contractor or distributor quantity, worth knowing before you order for a job that needs two or three transitions.
5) Is the Topaz 981S steel or die-cast zinc?
Steel. For rigid raceway in commercial and industrial work, panelboards, switchgear and motor control centers, steel holds up to the mechanical abuse and keeps the raceway electrically continuous through the size change.
6) Can I use a Topaz 981S enlarger at a panel or junction box knockout?
Yes, that's one of its common uses. Where a 1/2 inch run has to land in a 3/4 inch entry at a panel, junction box or other fitting, the 981S makes the transition right at the enclosure instead of partway back down the run.
