all of this conduit is to have a drop ceiling installed under it again...:censored:

We use compression on navfac and corps of engineers jobs as a spec but I think it's what our company prefers to get. I've tightened set screw couplings so tight that the conduit gets indented. Maybe they are concerned about wire skinning out when you pull the wire. Cooper makes the best compression fittings. Im disappointed in the American workers that make compression fittings that we use on govt. Jobs. I'd hate compression if I broke in with a lot of the crap out there right now

Man I was noticing the same thing. When I 1st broke in the trade the comp. couplings were fine. Now they seem like crap. I figured with the down economy they had stopped maintaining the machinery that makes them.

Sometimes I'd rather use comp coplings. Right now we're using set screw and it's pretty annoying grabbing some and 35% of them are missing their screw.

I've been getting a lot lately where the threads are bad and the screw is on an angle, gets expensive when you are tossing away 4 inch couplings because of it. Thomas and betts fittings too. Also been getting batches of couplings where some are missing the insulator on the throat. Not to mention some of the screws sometimes on the same fitting will not accept any screwdrivers because they are so poorly machined.

Now that Dad has passed away things will improve:whistling2:

I don't understand why they spec' out for compression? Does anyone know a good reason for this spec ?
Ive worked at a high security govt facility and they spec'd comp fittings because they were afraid "people" would slip microphones or cameras or something in there. They also had us put lb condolettes and c condolettes on both sides of fire rated walls then back fill them with spray foam.

Ive worked at an air force base and they didnt care about the raceway.

What we had to do was put filters on the wiring going into classified areas.

Kinda odd how there isnt a standard for the Government.

has anyone notice the length of the couplings and connectors for EMT conduit? Can they make them any shorter, you can barely fit the channels on them and your at the center of the coupling. You use the standard, trade size hole saw and the connector falls thru the hole.
