Has anyone run into this lately....... New old stock Appleton 1/2 EMT steel NOT die cast couplings. Had an occasion to "fish a run of 1/2 EMT" up an indoor chase in an older house today . I chose to use compression couplings, as I thought there was less of a chance of them getting caught on the way up.
All the couplings were definitely tight 2 pair of "channies", and the nuts would not move any further. 3 times the conduits fell of the couplings AFTER I got it all the way up to the 2nd floor attic. Investigation showed the compression rings completely tight.
Has anyone noticed maybe the EMT is thinner walled these days, hence a smaller outer diameter???? Set screw couplings tightened up fie. and the run is in.
Any ideas????
