L H Dottie Co NT350I Insulated No Thread Connector 3.5 in

Product Description

The L H Dottie Co NT350I is a 3.5-inch insulated no-thread connector used in electrical conduit installations where a clean, thread-free termination is required. This fitting seats conduit into a box or enclosure knockout without threading, speeding up rough-in work and reducing the chance of conduit damage from over-threading. The insulated design protects conductors from abrasion at the entry point. Electricians and electrical contractors reach for this type of connector during residential and light commercial wiring when working with EMT or similar conduit systems.

This connector is suited for standard electrical box and enclosure knockouts sized for 3.5-inch conduit. It fits typical applications in panel feeds, junction box terminations, and equipment enclosure entries. The no-thread design makes it a practical choice when working in tight spaces or when conduit must be terminated quickly without a die or threading machine on site.

Key Features

• Insulated throat protects wire insulation from abrasion at conduit entry
• No-thread design eliminates the need for a threading machine or die
• 3.5-inch nominal size fits standard knockouts of that trade size

Compatibility

Designed as an OEM-style replacement or new-install fitting for standard 3.5-inch electrical box and enclosure knockouts in commercial and residential conduit systems.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits in the enclosure before inserting or securing any conduit fitting. Ensure the knockout is free of burrs before seating the connector to maintain a secure fit and protect conductor insulation. Do not overtighten any locking ring or locknut beyond hand-snug plus one-quarter turn unless the fitting manufacturer specifies otherwise.
