Supports

Is this a bit odd for the supports? I'd think they should be stainless or pvc coated.

Are you thinking that a different material will last longer?

no. just thought stainless or pvc coated would make more sense because of the raceway type.

They did spec pvc coated

SS is difficult to source, expensive, and from what I’ve heard, difficult to work with. I have no experience with it however.

I would expect that the straps would be specified as PVC coated. Standard clamps will not fit correctly because of the increased outer diameter.
Note this type of installation requires additional labor, training, and special tools to prevent damage to the outer PVC protective surface. It is also expensive. Some specs require that the installer be certified by the PVC coated conduit manufacturer.

Thank you. So you're saying a two-piece strut clamp won't fit? Can't be.

Not properly, maybe if you changed the bolt to a longer one. But a PVC COATED clamp will fit properly and provide corrosion protection equal to the conduit.

You might make the next larger strut strap fit, but if you really need PVC coated rigid, that strap won't last two years.

B-line regular rigid straps usually work for me. Sometimes just have the squeeze them a bit with pliers to get the nut started.
