Thomas & Betts UV Resistant Tie Wraps: Any Experiences With For Out Of Door Usage ?

| Hi,
Was wondering if anyone has any experience using the "Premium" Thomas &
Betts, Black, "UV-Resistant"
nylon tie wraps out of doors ?
e.g., do they become brittle after a fer years due to very cold temps, or UV
?
Or, do they really hold up well, etc. ?
Thanks,
Bob

I live in Phoenix, they last a couple of seasons.
If your in a temperate region they might be ok.
We use a stainless steel band for outside work, in the desert sun.

To the OP or the casual reader, don't encircle any individual single
conductor cable in steel. All conductors of a circuit need to go through
together, such that the sum of the current encircled by steel is zero.
Otherwise the steel will heat from induced eddy currents. This is why
aluminum plates are sometimes used where multiple single conductor cables
enter (steel walled) enclosures. If individual conductors went through
individual holes in a steel enclosure wall, the steel would be subject to
heating.
