Allied Tube & Conduit SK125RKON – Frequently Asked Questions
1) Will the Allied Tube & Conduit SK125RKON coupling work with 1-1/4 inch EMT?
Yes. The SK125RKON is a 1-1/4 inch EMT set screw coupling, so it joins two runs of 1-1/4 inch electrical metallic tubing. It is sized for EMT only, not rigid or IMC conduit, which use threaded couplings instead.
2) Can a set screw EMT coupling be used in a concrete pour?
It is concrete tight when taped. For a slab pour, tape the joint so wet concrete cannot work into the coupling. Without tape it is not rated concrete tight, and for wet or damp outdoor locations a compression style fitting is the usual choice instead of set screw.
3) Does a set screw EMT coupling need a tool to tighten, or are the screws pre-installed?
The screws come pre-set and staked in the coupling on sizes 1/2 inch through 2 inch, which covers the 1-1/4 inch SK125RKON. You slide the tubing in from each end and tighten the tri-head screws down onto the EMT. Larger trade sizes, 2-1/2 inch through 4 inch, use hex head screws instead.
4) Is the SK125RKON coupling steel or die cast?
It is built with heavy steel walls, not zinc die cast. Steel set screw couplings hold up better to being stepped on or struck on a job site and are what most commercial and industrial specs call for over die cast.
5) What part number do I order for a 1-1/4 inch EMT set screw coupling from Allied Tube & Conduit?
Order SK125RKON. That is the Atkore Allied Tube & Conduit manufacturer part number for the 1-1/4 inch EMT set screw coupling. The SK prefix is the set screw coupling line and 125 is the 1-1/4 inch trade size.
6) Does an EMT set screw coupling provide an equipment ground path?
Steel EMT with steel fittings is used as an equipment grounding conductor, and the heavy steel walls of this coupling carry that path when the set screws are tightened firmly onto clean tubing. If your spec calls for a separate green wire ground, the coupling does not replace it.
