Thanks fellas,<br>I guess I was not clear. We are using RMC or IMC on all of are roof top runs with the appropriate expansion fittings. I am trying to figure out how to deal with the movement of the conduits at the bases where we strap it down to the base( a curb with a small peice of shallow b-line placed on it (4') ).<br>
