About Conduit

Access Ports for Metal Conduit

Also known as conduit bodies, these ports provide access to wire and cable inside conduit for pulling, splicing, and maintenance. They are also used to change the direction of a run. Connect to thick-wall (rigid) metal conduit. Aluminum and zinc-plated iron ports can connect to medium-wall (IMC) conduit. Ports with a set screw also connect to thin-wall (EMT) steel conduit without a compression connector.

All are corrosion resistant. 316 stainless steel ports offer the best corrosion resistance.

Ports that can be configured as a straight, tee, or 90° elbow come with multiple cover plates for openings not in use. They are UL listed raintight for thick-wall (rigid) conduit and concrete-tight for thin-wall (EMT) conduit.
