Appleton SNTCC-100 Set Screw Conduit Coupling 1 Inch

Product Description

The APPLETON SNTCC-100 is a set screw, threadless conduit coupling designed to join lengths of rigid metal conduit (RMC) or intermediate metal conduit (IMC) without threading. Constructed from steel with a concrete-tight rating, this coupling meets the demands of commercial and industrial conduit installations where secure, moisture-resistant connections are required. The 1-inch trade size fits standard 1-inch RMC and IMC. It carries UL and CSA C22.2 approvals and is rated for Class I, Division 2 hazardous locations. Electricians install it as a fast, reliable alternative to threaded couplings in above-slab and embedded concrete applications.

The SNTCC-100 is suited for use in commercial, industrial, and residential electrical installations that require rigid metal conduit or IMC raceway systems. Its concrete-tight construction makes it appropriate for slab and embedded conduit runs. The set screw design eliminates the need for threading tools on-site, speeding up installation in new construction and retrofit projects. Applications include feeder runs, branch circuit raceways, and conduit systems in exposed or concrete-encased environments.

Key Features

• Set screw, threadless design joins RMC or IMC without pipe threading
• Steel construction for durability in commercial and industrial environments
• Concrete-tight rating suitable for embedded and slab conduit runs
• Rated for Class I, Division 2 hazardous locations
• UL listed and CSA C22.2 approved for code-compliant installations
• 1-inch trade size for standard 1-inch RMC and IMC

Compatibility

Designed for use on 1-inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC) per the raw product data. Suitable for threadless conduit systems where concrete-tight coupling is required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the conduit run before making connections. Tighten set screws to secure the coupling to both conduit ends; do not overtighten to the point of deforming the conduit wall. Verify the concrete-tight rating meets the requirements of the installation environment before embedding in concrete.
