Works well but not perfect

These connectors work as intended and keeps the cable secured in junction box. Competitively priced for bulk quantities. Several did not have any screws. Mostly used for 14/2 and 14/3 MC cables in my application and felt the clearance hole was a bit too big and sometimes the screw would grab the edge of the armored sheathing instead of the center so you just got to pay attention. 12/2 and 12/3 definitely fits better even with the plastic bushings installed. The screws were tight so just work them beforehand prior to installation.

I am using these to handle Armorlite 14/2 cable. The opening is still bigger than I would like despite the manufacturer's recommendation that these work for this type of cable. I am rewiring our church camp and have tried many clamps for the Armorlite cable and none work great. These do at least secure the cable well and should not pull out of the clamp like some of the other fittings I have used. I would like something slightly better but these are doing a pretty decent job.

Why are your reading the reviews on MC connectors?

There MC connectors, what more is there?The screw turns and all the connectors came with a locknut.

Worked as expected with TORCHSTAR 18W 6 Inch LED

These were used to secure 3/8” metal-shielded electrical cables to the junction boxes of the TORCHSTAR 18W 6 Inch LED. They could have easily handled 1/2inch cable. Very well made.

Set screw issues

I'm an Electrician and i know how these things are supposed to work. I must say that they do get the job done, But, the set screws are a Whole new animal, A total pain trying to tighten them, You can get seriously hurt. I have to lock them in a Vice and use an impact screw driver to free the screws up, but after that, they work nicely.
