My current job requires more large diameter (3" and 4")emt than I have ever faced before. The problem I'm having is getting a good grip on the coupling nuts with the tools that I have.

What do you suggest for large couplings?

I've tried pipe wrenches, large channel-lock pliers, and a chain wrench, none of these seems very effective. Suggestions???

How about a 24" aluminum pipe wrench to cut down on the weight?

If all couplings the same can you use a mini socket driver? If the couplings have a slot for a flat screw driver klein makes a Hooded screwdriver that I have found to work really decent. It also has a conduit reamer built onto it for 1/2,3/4,1 inch. Again, there are so many types of manufacturers that it is tough for the "one tool for the job". Hope this helps. I will try to get a picture of the tool. Oh yeah and you might want to try the mini set of Robo Grips. They work well when in tight spots.

I guess after reading the main post again I need to ask what the heck a coupling nut is. I figured it was the set screw. Call them locknuts where I am from.

I think he means they are using a lot of 3" and 4" compression couplings, instead of the set screw couplings. You know nut on one side nut on the other side and fitting nut in the middle. Big channel locks is about the only way to go. My hooded screwdriver won't fit the set screws on 3" fittings, do they make more than one size?

I would take a 5 iron and hit a low hard draw.Oops wrong board.Ridgid makes some medium sized strap wrenches that work well so do the 470 and 480 channellocks.I have also found that if you put the coupling on one end of your conduit on the ground you only need one set of pliars in the air most of the time

I've got to agree with Bjarney and fedup. 480 Channelocks.

Ah, didn't realize he was using compression fittings. [Linked Image] Has any one tried that strap wrench from sears?
And to Joeh20: I have indeed found 3 inch couplings that the hooded screwdriver works but only on kind and that was a year ago. So many different brands out there. Why doesn't Klein make a hooded screwdriver that will fit "All Larger Brands of setscrew couplings.(but moreover why do they continue to use flat head set screws???) It really isn't a bad idea but like you said, hard to find couplings to fit the screwdriver over.
