Strut clips that allow PVC to move

[iwire]

I had to install a bunch of these in the last few days, I was not even sure they made them until looking in a B-Line catalog.

352.30 Securing and Supporting. PVC conduit shall be
installed as a complete system as provided in 300.18 and
shall be fastened so that movement from thermal expansion or
contraction is permitted. PVC conduit shall be securely fastened
and supported in accordance with 352.30(A) and (B).

So do you use a standard clamp within 3' of a box to comply with 352.30(A)?

Cool, I never saw them before.

Well actually we just left the standard clamps in place at the boxes, this was a retro-fit.

And yes, I know ......... our guy tightens stuff too much. He does use a torque wrench on electrical connections.

I didn't even notice the screws on the straps until I read this post and scrolled back up. Good grief. I think you should only allow him to use a screwdriver on strut straps.

You think he was trying to get them tight enough where the pipe wouldn't move?

Yes, that is the part.

I'd like them a lot better if they had some type neopreme or gasket material on the inside of the instide stap so they could be snug yet still move.

I never did like the way the pipe hangs so loose in the strap.

To me, no matter how fancy the strap,Pvc doesnt look good running along an outside wall.

I really don't see why.

It is no supposed to secure it, only support it.

I hear you, if it was up to me PVC would stay underground.

Your right about the support thing. We could use 6" 2 hole straps to support it, but it would look even worse yet.
