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

Hi Bob:

I have no experience with that brand, but I've used UV resistant (black tie
warps) for years.
The feedlines on my tower are held up with them and I've noticed no
degradation in them for the last 4 years. For what its worth, in the past
I've used Scotch #33 black electrical tape and it has held hard-line and
coax to my tower for 5 to 6 years with no problem. Some professionals I know
use electrical tape for all but the largest runs of hard-line.

My experience with the black UV resistant ties from many manufacturers
is that they do last years in direct sunlight. ... don't even compare
with white ties that will degredate within a single year.

Also, a Blue colored tie has been available for some time that is
supposedly guarantied to last up to 15 years outdoors. Having used them
in years past, it does appear to be true... although they are quite
expensive. I forget the manufacturer.

In years past many techs have just used short lengths of insulated
12guage solid wire to hold feedlines to a tower. This is still a valid
way to go.... cheaper than ties, and they last very long, too.

Black tie wraps do definately hold up longer than regular tie wraps, but
will still give up after several years. Used to use them for Telephone
cables, as well as coax. Wish I remembered the brand name , but if you
Permanent ties, there is a make of METAL- plastic coated ties, that 1) last
forever, and 2), can be reused. Try Greybar Electric , and W.W.
Grainger. Tiewraps are also available in different colors, (they were
used to mark multi -pair telephone cables, in 25 pair bunches), which
are great for clean installs of wireing, in vehicles (blend in with the
vehicle colors), makeing them nearly invisible.

I'll bet Panduit was the likely name for them! They are one of the
larger makers of all kinds of ties, plastic, metal, etc. I used them for
decades. Do a Google search for Panduit Tie wrap and see what turns
up.

I worked at an electrical supply for several years, and When Georgia Power
was building Plant Vogtle nuclear plant, they must have purchased a
truckload or more TY-525-MX (black WP tie-raps). Paperwork had to be
traceable back to the factory. We also sold a lot of of Panduit brand
tie-raps. I think they are of equal quality.
The black ones have carbon in the mix to retard UV damage. If you take one
more step (like put a wrap of tape (3M#88) over the tie-rap) or even paint
it - it should give more years of life.
--but like one post mentioned - Panduit -and T&B if I recall both have
stainless steel versions.

I used to sell the things in large quantities while working for a
Cincinnati electronics distributor. The T&B's are pricey, but for a
reason. They have a stainless steel barb to lock the ty-wrap (their
trademarked name for the devices). It is much stronger than most
competitors molded nylon barb. The black, uv treated ty-wraps work
very, very well. I'll admit that as a radio amateur, I use the generic
uv resistant ones and they also do the job. I generally tape over them.

That's right. but the regestered name is TyRap. TY525M was the best selling
one we sold.

I often use the solid-wire trick. I'd note that if you use multiple
turns--two or three or four-- it will hold much tighter than a single
turn, allowing use of easier-to-handle smaller gauges to hold the same
load. It's also a lot easier than a tie-wrap to UNdo when the time
comes--no tools required. Easily available in black and white (in the
US at least), and other colors if you want. Scales to different sizes
well, too. Not that I don't use tie-wraps too, but sometimes they
aren't quite the right choice. Oh, and I've recently gotten some
easy-release reuseable tie-wraps -- black, and reasonably easy to use,
though a larger "knob" of plastic at the latch point. Dunno how many
times they can be released/re-used yet.

Cheers,
Tom
