Allied Tube & Conduit SC400RKON – Frequently Asked Questions
1) What size EMT does the Allied Tube & Conduit SC400RKON set screw connector fit?
The SC400RKON is a 4 inch EMT set screw connector, so it takes 4 inch electrical metallic tubing only. Smaller trade sizes need the matching connector in that size.
2) Can a 4 inch EMT set screw connector be used in a concrete pour?
Only if it is taped. Allied rates the set screw connector as concrete tight when taped, so the joint has to be wrapped before the pour. Without tape it is not a concrete tight fitting, and a compression connector is the usual choice for wet or poured locations.
3) Does the 4 inch SC400RKON connector use tri-head or hex head set screws?
Hex head screws. Allied uses pre-set and staked tri-head screws on the 1/2 inch through 2 inch connectors, and hex head screws on 2-1/2 inch through 4 inch, so the 4 inch SC400RKON tightens with a hex driver or nut setter.
4) Set screw or compression connector for 4 inch EMT, which should I order?
Set screw fittings like the SC400RKON are the standard, faster, lower cost choice for dry indoor runs, and they are concrete tight when taped. Compression connectors are what you want where the location is damp or wet, since a set screw fitting on its own is not raintight.
5) Is the SC400RKON steel or die cast?
Steel. Allied builds this 4 inch EMT set screw connector with heavy steel walls, which is what holds up on large trade size runs where the fitting carries real weight from the tubing.
6) What part number do I order for a 4 inch Allied EMT set screw connector?
Order Allied Tube & Conduit SC400RKON. That is the manufacturer part number for the 4 inch EMT set screw connector, and it is a single configuration, no finish or option codes to add.
7) Does this 4 inch EMT connector come with a locknut for the box?
The SC400RKON is a connector body with its hex set screws; plan on a 4 inch locknut and, where your spec calls for it, an insulated throat bushing to land it in the enclosure.
