Atkore Allied Tube & Conduit SC100-ICRKON 1" EMT Set Screw Connector With Insulated Throat

The SC100-ICRKON is a 1 inch EMT set screw connector. It terminates 1 inch electrical metallic tubing into a box or enclosure; for other trade sizes you need the matching size in the series, not this one.

Concrete tight when taped. The Allied Tube & Conduit set screw connectors are rated concrete tight provided the joint is taped, so for slab work you tape the fitting before the pour. If you want a compression style fit without taping, that is a different connector type.

No. This is a 1 inch EMT set screw connector, made to clamp onto electrical metallic tubing. Rigid and IMC thread into their own fittings, and FMC or liquidtight needs a connector built for that jacket. Match the fitting to the raceway type.

The insulated throat on the SC100-ICRKON gives conductors a smooth non-metallic bearing surface at the point where they enter the box, so pulling THHN through a 1 inch run does not drag insulation across a raw steel edge. Many jobs spec insulated throat connectors for that reason; a standard uninsulated set screw connector is otherwise the same fitting.

Sizes 1/2 inch through 2 inch, which includes this 1 inch connector, ship with pre-set and staked tri-head screws, so the screw is already in place and captive when you pull it out of the box. Larger fittings, 2-1/2 inch through 4 inch, use hex head screws instead.

Atkore Allied Tube & Conduit part number SC100-ICRKON. That covers the 1 inch trade size with the insulated throat.

The SC100-ICRKON is the connector body itself, built with heavy steel walls. Order the locknut separately if your box knockout needs one, along with any bushing your spec calls for.
