Nsi Industries 258-DC2 Compression Connector 3.5 in Crafted

The NSI INDUSTRIES 258-DC2 is a compression-type electrical connector measuring 3.5 inches in length. Compression connectors are used to create secure, low-resistance terminations between conductors or between a conductor and a fitting, without requiring soldering or threading. This style of connector is a staple in electrical installation and maintenance work, used by licensed electricians and electrical contractors across residential and commercial projects. The compression design ensures a consistent mechanical connection that resists vibration loosening and pull-out forces common in wiring installations.

The 258-DC2 is suited for use in conduit and wiring applications where a reliable compression fitting is required. It is typically installed in junction boxes, conduit runs, and enclosure entries. The 3.5-inch form factor accommodates standard conduit and cable entry configurations found in both new construction and retrofit electrical work.

Key Features

• Compression-type design provides a secure, tool-made termination without soldering
• 3.5-inch length fits standard conduit and enclosure entry configurations
• Low-resistance connection suitable for electrical conductor terminations
• Designed for durability in typical indoor and outdoor electrical installations

Compatibility

Designed as an OEM-style replacement or standard compression connector for use in residential and commercial electrical conduit and wiring systems.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit completely and verify with a voltage tester before beginning work. Use the appropriate compression tool to achieve a proper crimp or compression seal. Avoid over-compressing the fitting, as this can damage the conductor or connector body.
