Allied Tube & Conduit CKR-350KON – Frequently Asked Questions
1) Is the Allied Tube & Conduit CKR-350KON coupling rated for outdoor or wet locations?
Yes. The CKR-350KON is a raintight compression coupling, rated for use in wet locations, so it's suitable for exposed outdoor EMT runs. It's also concrete tight, which means it can be used in poured slabs and walls.
2) What size conduit does the CKR-350KON compression coupling join?
It joins 3-1/2 inch conduit, coupling two runs end to end with compression nuts rather than set screws. Compression is the connection style you want where water can get in, since the gland seals around the tube.
3) Do I need a set screw coupling or a compression coupling for outdoor EMT?
Set screw couplings are for dry indoor locations only. For anything exposed to weather you need a compression fitting like the 3-1/2 inch CKR-350KON, which is raintight in wet locations. Compression also holds up in concrete pours where a set screw fitting would let in moisture and slurry.
4) Why does the CKR-350KON have a blue nut?
The blue nut is an identification feature. On a job with both dry-location set screw fittings and raintight compression fittings in the same gang box, the blue nut lets an inspector or another electrician see at a glance that the fitting is the raintight compression type. It has no effect on how the coupling installs.
5) Is this 3-1/2 inch coupling heavy enough for a commercial exposed run?
It's built with heavy steel walls, which is what you want on large trade sizes where the fitting takes the weight and torque of a 3-1/2 inch run. Combined with the raintight and concrete tight ratings, it's a fitting intended for exposed and embedded commercial work rather than light indoor use.
