Allied Tube & Conduit SK150RKON – Frequently Asked Questions
1) Will the Allied Tube & Conduit SK150RKON couple two pieces of 1-1/2 inch EMT?
Yes. The SK150RKON is a set screw coupling sized for 1-1/2 inch EMT, so it joins two runs of 1-1/2 inch electrical metallic tubing. It is a set screw design, not compression, so the tubing ends are held by screws rather than a gland nut and ferrule.
2) Does a 1-1/2 inch EMT set screw coupling have one screw or two per end, and are the screws included?
Screws come installed. On Allied Tube & Conduit set screw couplings in the 1/2 inch through 2 inch sizes, which covers the 1-1/2 inch SK150RKON, the screws are pre-set and staked tri-head. The 2-1/2 inch through 4 inch sizes use hex head screws instead. Nothing extra to order to make up the joint, just a driver that fits a tri-head screw.
3) Can I use a set screw EMT coupling in a concrete pour?
The SK150RKON is concrete tight when taped. That means the joint qualifies for encasement in concrete only if you tape over the coupling before the pour. Untaped, treat it as a dry indoor coupling. For wet locations or direct burial where taping is not practical, use a compression style EMT coupling instead.
4) Set screw or compression coupling for 1-1/2 inch EMT, which should I be buying?
Set screw, like the SK150RKON, is the faster and more common choice for dry interior work such as exposed runs in commercial ceilings, mechanical rooms, and walls. It is concrete tight only when taped. Compression couplings are what you specify for damp or wet locations and where a raintight joint is called for. If the drawing says raintight or concrete tight without taping, the set screw version is the wrong part.
5) Is this 1-1/2 inch coupling steel, and is it heavy enough for exposed commercial runs?
It is built with heavy steel walls, which is what you want on an exposed 1-1/2 inch run where the coupling can take a knock from a lift or a cart. Steel also keeps the raceway continuous for equipment grounding through the conduit system.
