3 Piece Coupling..

[kwired]

Right out of the box it's opened enough to slide right over the end of the conduit. Once you make up the bolts it clamps tightly onto the threads. We've used these over the three piece Erickson type because they're so much easier and faster. Just slide into position, grab an impact gun and you're done. I was always under the impression that they were cheaper than the 3 piece type but mrlucky told me that they are not. I would still use them because they save on expensive labor costs.

My guess is they probably don't make them much smaller than 2" trade size either? Nearly every Erickson I have used was 1/2 or 3/4.
