The NSI INDUSTRIES 410 is a 1-inch squeeze-type flexible conduit connector used to terminate flexible metal conduit to electrical boxes, enclosures, and panels. The squeeze-type design eliminates the need for a screwdriver during installation, allowing the connector to be secured with hand pressure alone. This fitting is a standard component in commercial and residential electrical work where flexible conduit terminations are required. Electricians use this connector wherever flex conduit transitions to a junction box, load center, or device enclosure.
This connector is suited for use in residential and light commercial electrical installations. It is commonly installed in applications where flexible metal conduit is used to connect motors, appliances, HVAC equipment, or other loads to a fixed raceway or panel. The 1-inch trade size fits standard 1-inch flexible metal conduit, making it a frequently specified fitting for a wide range of service work and new construction.
Designed as an OEM-style replacement and standard-use fitting for 1-inch flexible metal conduit terminations at electrical boxes, enclosures, and panels.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and lock out the panel before making conduit connections inside any enclosure. Verify that the knockout opening matches the 1-inch trade size before inserting the connector. Ensure the conduit is fully seated and the connector is properly secured before restoring power.
