About Conduit

Adapters for Flexible Metal Conduit

Attach flexible metal conduit to a knockout in an outlet box or enclosure. The screw-clamp end tightens around conduit with a screw. Iron adapters are stronger and more durable than zinc adapters. 316 stainless steel adapters are the most corrosion resistant.
