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.

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.
