use a mini bolt the mini to b-line and use mini that is to large and when tight
will allow the conduit to slide. also I have used a B-line clamp that was ment
not to slide.

Thanks fellas,
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') ).
