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

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.
