About Conduit

Adapters for Thin-Wall (EMT) Steel Conduit

Use these adapters to attach thin-wall (EMT) steel conduit to a knockout in an outlet box or enclosure. A compression end offers a more reliable hold on conduit than a screw-clamp end. It pushes onto the conduit; tighten the compression ring to secure. The screw-clamp end tightens around conduit with a screw.

Adapters with grommet protect wire and cable from abrasion when being pulled.

Adapters with O-ring prevent liquid from entering the conduit. They meet UL raintight standards when used with EMT conduit.
