Appleton IBC-350LS-20AC Insulated Bushing 3.5 in

Product Description

The APPLETON IBC-350LS-20AC is an insulated bushing designed to protect wire and cable insulation at the ends of threaded metal conduit. The bushing seats inside the conduit end and provides a smooth, non-conductive surface that prevents abrasion and nicking of conductor insulation during pull-in and throughout service. Sized for 3.5-inch conduit, this fitting is a standard component in commercial and industrial conduit installations where wire protection at termination points is required by electrical codes. Licensed electricians and electrical contractors install this part as part of a compliant conduit end-treatment assembly.

This insulated bushing is suited for use in commercial buildings, industrial facilities, and infrastructure projects where 3.5-inch rigid metal conduit or intermediate metal conduit terminates at enclosures, panels, or junction boxes. It is appropriate for both new construction rough-in work and retrofit or repair situations where existing conduit ends require a replacement bushing to meet inspection requirements.

Key Features

• Fits 3.5-inch threaded conduit ends for secure, code-compliant wire protection
• Insulated interior surface reduces risk of conductor insulation damage during wire pull
• Low-profile design accommodates standard enclosure and panel knockouts
• Lightweight at 0.57 pounds for easy single-hand installation in tight spaces

Compatibility

Designed as an OEM-style replacement insulated bushing for 3.5-inch threaded rigid metal conduit and intermediate metal conduit terminations in standard electrical installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements for conductor protection at conduit ends. De-energize the circuit and lock out the panel before beginning any conduit termination work. Thread or seat the bushing firmly onto the conduit end before pulling wire to ensure full conductor protection. Inspect the bushing for cracks or damage before installation and replace if the insulated surface is compromised.
