Allied Tube & Conduit SK250RKON – Frequently Asked Questions
1) Does the Allied Tube & Conduit SK250RKON coupling use set screws or a compression ring?
It's a set screw coupling, not compression. On the 2-1/2 inch size the screws are hex head, so you tighten them with a nut driver or socket rather than a screwdriver. Allied pre-sets and stakes tri-head screws only on the smaller 1/2 inch through 2 inch couplings; from 2-1/2 inch up through 4 inch the screws are hex head.
2) Can I use a 2-1/2 inch EMT set screw coupling in a concrete pour?
Only if you tape the joint. The SK250RKON is rated concrete tight when taped, so wrapping the coupling and both conduit ends before the pour is required for that rating. Left untaped, treat it as a dry indoor coupling. It is not a rain tight or wet location fitting.
3) Is this a steel coupling or die cast?
Steel. Allied builds the SK250RKON with heavy steel walls, which is what contractors specify for larger trade sizes where a die cast body can crack under wrench torque or when the conduit gets racked during a pull.
4) Do I need a set screw or a compression coupling for 2-1/2 inch EMT?
Set screw fittings like the SK250RKON are the normal choice for dry, indoor, exposed or above-ceiling EMT runs, and with tape they hold up in a concrete pour. If the run is outdoors, in a damp location, or anywhere a rain tight joint is called for, a set screw coupling is the wrong fitting and you want a compression (gland nut) coupling instead.
5) What part number do I order for a 2-1/2 inch EMT set screw coupling from Allied?
SK250RKON is the Allied Tube & Conduit (Atkore) catalog number. That single number covers the coupling as supplied, with its screws installed, so there is no separate hardware to add to the order.
