Allied Tube & Conduit SEC250KON – Frequently Asked Questions

1) Can I use the Allied Tube & Conduit SEC250KON to join threaded rigid conduit to unthreaded EMT?
That is exactly what the SEC250KON is built for. It's a 2-1/2 inch three piece compression coupling that connects threaded IMC or GRC to threaded or unthreaded EMT, IMC or GRC, so you can tie a threaded rigid run into a plain cut end of EMT without re-threading or swapping to a different fitting. It also handles threaded to threaded and unthreaded to unthreaded joints.
2) What conduit size does the SEC250KON super fitting take?
It's the 2-1/2 inch size in the Allied Tube & Conduit super fitting line. Both ends are 2-1/2 inch, so it couples 2-1/2 inch EMT, IMC or GRC, in any combination of threaded and unthreaded ends. For other trade sizes you need the corresponding fitting in the series, not this part number.
3) I have a cut length of 2-1/2 inch EMT and no threading equipment on site. Will this let me couple into an existing threaded rigid run?
It will. Because the coupling accepts an unthreaded end on one side and a threaded IMC or GRC end on the other, a field cut piece of 2-1/2 inch EMT goes straight into it with no threading and no need to break the fitting down. That is the usual save on a repair or a change in a finished ceiling.
4) Do I have to take the coupling apart to install it on a conduit run?
No. The three piece compression design installs without disassembling the fitting, which is the point of it on a repair or tie-in where you can't pull the conduit back to get a standard threaded coupling started. You slide it on and tighten the compression ends.
5) Can one of these replace the rigid hubs and reducing fittings I normally stock for 2-1/2 inch repairs?
Yes, and that's the reason contractors buy it. Allied markets the super fitting as one fitting that replaces various rigid hubs and fittings, because the same coupling covers threaded and unthreaded ends across EMT, IMC and GRC. For a truck stock or an MRO crib, a single 2-1/2 inch SEC250KON line item takes the place of several single purpose couplings and hubs.
6) What part number and manufacturer do I put on the order for the 2-1/2 inch Allied super fitting coupling?
Order it as Atkore Allied Tube & Conduit, MPN SEC250KON. That is the 2-1/2 inch three piece compression coupling in the steel super fitting line, sold as a single fitting with no size or finish options to specify.
7) Is this a steel fitting or die cast?
Steel. Allied calls it a steel super fitting, which is what you want when the coupling has to match a steel raceway system of EMT, IMC or rigid galvanized conduit.
