Appleton NTC100 Rigid Compression Conduit Connector

Appleton NTC100 is a 1-inch trade-size, threadless rigid conduit compression connector used to terminate rigid metal conduit (RMC) or IMC into an enclosure or junction box. It uses a compression fit with a non-insulated throat and a zinc-electroplated malleable-iron body (some catalogs list steel) for durability in commercial and industrial installations. Verified retailer specs commonly list an overall length of about 3.13 inches, a body diameter near 1.88 inches, and a throat diameter around 0.56 inches. The connector is UL 514B listed and CSA C22.2 certified for use with rigid or IMC conduit, ensuring compatibility with standard conduit systems. As a threadless compression connector, it clamps onto the conduit and is secured to the enclosure via the compression nut, providing a tight, mechanically sound and electrically continuous termination in metal conduit installations.
