Allied Tube & Conduit SC250RKON – Frequently Asked Questions
1) Will the Allied Tube & Conduit SC250RKON connector work with 2-1/2 inch EMT?
Yes. The SC250RKON is a 2-1/2 inch EMT set screw connector, sized for 2-1/2 inch electrical metallic tubing. It clamps the tubing with a set screw rather than a compression ring, so there is no separate gland nut or ferrule to keep track of on the job.
2) Can I use a set screw EMT connector in a concrete pour?
The Allied SC250RKON is concrete tight when taped, meaning the joint has to be taped at the connector before the pour to keep wet concrete out. Untaped, a set screw connector is not a concrete tight fitting. If you would rather not tape every fitting on a slab deck, a compression type EMT connector is the usual alternative.
3) Does the SC250RKON use a hex head or a tri-head set screw?
At 2-1/2 inch it takes hex head screws. Allied uses hex head screws across the 2-1/2 inch through 4 inch sizes, while the smaller 1/2 inch through 2 inch connectors come with pre-set and staked tri-head screws. So bring a nut driver or socket for this one rather than a flat blade.
4) Set screw or compression EMT connector for a 2-1/2 inch run?
Set screw fittings like the SC250RKON go on faster and cost less, and they are the standard choice for dry interior work such as exposed runs in mechanical rooms, above accessible ceilings, and in walls. Compression fittings are what you reach for in damp or wet locations and where a raintight joint is required. For concrete, the SC250RKON qualifies as concrete tight only when the joint is taped.
5) Is the SC250RKON steel or die cast zinc?
It is built with heavy steel walls, so this is a steel connector rather than a die cast fitting. That matters on a 2-1/2 inch trade size, where the fitting body takes real handling abuse during pulls and gets stepped on before the run is dressed in.
6) Does the SC250RKON connector come with the locknut for the box knockout?
Allied set screw connectors of this type are supplied with the fitting and its set screw hardware; plan your box hardware separately if your spec calls for an insulated throat bushing or a grounding locknut on the 2-1/2 inch knockout. The connector itself is the transition from 2-1/2 inch EMT into the enclosure.
