Expansion Fittings/straps

[Robz]

What type of strap or hanger do they make to strap a 4" PVC schedule 40 conduit to the wall outside (to run the conduit horizontal )that allows for expansion and contraction? When I contacted our local supplyers they told me they do not know of any strap that will allow the conduit to move?

PVC conduit exposed is not good. Get over it.

I believe the plastic straps are meant to allow expansion
and contraction, e.g. Carlon straps at:
http://www.carlon.com/Product_SupportStrapsClamps.html
state:
...clamp allows conduit to expand and contract freely, eliminating the bowing commonly seen from the expansion and contraction of conduit caused by varying temperature changes ...

I'm assuming you said this because you are in Florida (Sunshine State).

I see an example of exposed, badly warped PVC (sched 40, sked 80) conduit everyday as I traverse our bridges in Brevard County, Florida. I mean really gnarly looking installs.

Yes, sir I did. I may have spoken out of turn here. What happens in other climates?

Can you provide an example of a really good exterior install?

Doubt it . . .

The stuff belongs underground, in a ceiling, or if exposed outside, at least paint it!
