Wrenches,

I have used Carlon Carflex for years with no problems. In the Colorado mountains we do not see the hot days that would drive back of module to 75 C. Recently tried Heyco Heyco-Flex II on a few projects. It has a temperature rating of 70 C (no wet/dry distinction in the catalog). It is more flexible than the Carflex so hopefully will reduce strain on the j-box. Standard color is black. Somewhat more expensive than Carflex.

It is hard for me to imagine wiring modules intended to last for 20 years plus in anything other than conduit. I just don't have the confidence in USE-2 or TC, in terms of resistance to the elements or critters.

Bill Brooks, what non-metallic LT products have an 80 C wet rating? I haven't come across any. The 75C back of module -- is that module back surface temperature or conduit ambient?

I'll be out of town most of this week, so won't be able to respond til later.
