About Conduit

Medium-Wall (IMC) Steel Conduit

For technical drawings and 3-D models, click on a part number.

Conduit

Also known as intermediate metallic conduit (IMC), this conduit is lightweight and strong. A smooth coating protects wire and cable from abrasion when being pulled. This conduit has one threaded male end; the other end has a threaded female connector.

5-ft. lengths can be shipped via small-parcel carrier.

Round Adjustable-Length Shipping Tubes

Adjust these tubes by twisting the two halves. A hexagonal end prevents rolling. Use them to protect long, thin objects during shipping.

Twist-to-lock tubes can be slid up or down to adjust their length, so you don’t have to repeatedly twist the two pieces. To slide, turn the top tube into the sliding channel. To lock, turn the tube with the ridges into the grooved channel.
