Three-Piece Couplings for IMC /RSC Conduit
- Standard: UL 514B
- Material: Zinc die cast, Steel, Hot dip galvanized steel
This type of coupling consists of three main components:
- Outer Sleeve: The outer sleeve is a cylindrical metal piece with threaded ends. It acts as a sleeve that covers the joint between the two sections of conduit, providing protection and structural support.
- Inner Sleeve: The inner sleeve is a smaller cylindrical metal piece with threaded ends that fits inside the outer sleeve. It is used to join the two sections of conduit together. The inner sleeve is typically inserted into the ends of the conduit sections and tightened with a wrench.
- Set Screws: The set screws are small screws that are inserted through holes in the outer sleeve and tightened against the inner sleeve. They provide additional stability and secure the inner sleeve inside the outer sleeve, ensuring a tight and secure connection between the conduit sections.
The three-piece coupling provides a durable and robust connection between IMC or RSC conduits, ensuring proper alignment, support, and protection for the electrical wiring. It allows for easy installation and maintenance of the conduit system while maintaining the necessary mechanical and electrical continuity.
