Appleton KC-300 3-inch Flexible Conduit Connector

Product Description

The APPLETON KC-300 is a 3-inch flexible conduit connector designed for use in electrical conduit systems where vibration isolation or directional transition is required. This 2-screw style connector provides a secure mechanical attachment point between flexible metallic conduit and an enclosure knockout or fitting. Licensed electricians and electrical contractors install this type of fitting during rough-in and finish wiring on commercial and industrial projects. The connector weighs 2.9 pounds and measures 4.25 inches on each side, making it a substantial, rigid-duty fitting suited for larger conduit runs.

This connector is used in applications where 3-inch flexible metallic conduit terminates at a panel, junction box, motor enclosure, or equipment housing. The 2-screw clamping mechanism allows for straightforward field installation without specialized tooling. It is appropriate for commercial construction, industrial facilities, and equipment installations where conduit flexibility is needed at connection points to reduce vibration transmission or accommodate minor misalignment between rigid conduit runs and equipment.

Compatibility

Designed as an OEM-style fitting for use with 3-inch flexible metallic conduit in standard commercial and industrial electrical installations. No specific compatible enclosure or conduit model numbers were identified in the product data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and verify with a meter before beginning work on any enclosure or panel where this connector will be installed. Ensure the knockout size on the enclosure matches the 3-inch trade size before insertion. Tighten the 2-screw clamp evenly to secure the conduit without deforming the conduit jacket or fitting body.
