Thomas & Betts 8853 Threadless Conduit Connector

Description:

The Thomas & Betts 8853 Threadless Connector is used to connect and effectively bond 3-1/2-inch rigid metal conduit (RMC) or intermediate metal conduit (IMC) to electrical boxes and enclosures without threading the conduit. Commonly installed in industrial facilities, commercial buildings, power distribution systems, and heavy-duty electrical installations, this insulated threadless connector features a malleable iron body with a nylon-insulated throat to protect conductors while providing a concrete-tight connection. Electricians, maintenance technicians, and electrical contractors use this fitting for new installations, repairs, retrofits, and replacement of rigid conduit connections.

Applications:

The Thomas & Betts 8853 is designed for terminating 3-1/2-inch threadless rigid metal conduit or IMC into electrical enclosures, junction boxes, switchgear, and panelboards. Its split steel ring provides positive grounding and mechanical retention without requiring conduit threading, making it ideal for industrial plants, commercial facilities, utility installations, manufacturing equipment, and concrete-embedded conduit systems.
