I think that jives with my theory. We're using them because we've always used them. Since I can print out a non-conductive, self-extinguishing vinyl wire marker<https://tds.bradyid.com/TDSdocs/B-427.pdf> label on demand these tags aren't really important anymore. They're just still in various companies' cabling specs so we keep using them.
I wonder what they used before that made "non-conductive" a noteworthy feature of the 145P. Steel dog tags? Wet paper? Cuneiform on clay tablets? ________________________________ From: AF <[email protected]> on behalf of [email protected] <[email protected]> Sent: Monday, June 30, 2025 2:09 PM To: 'AnimalFarm Microwave Users Group' <[email protected]> Subject: Re: [AFMUG] Question for old phone guys - Why 145P tags? I have been in the industry since 1978 and they way predate me. The ones that I used were made out of a compressed fish paper which is highly fire resistant. Frequently connected with a brass ring to whatever it is they were marking. They came in a kit with ink and a stencil to hand lettering the tags. Kinda like leroy lettering. Very durable.

How long have telcos been using these 145P tags, and what's the origin story? [cid:[email protected]] I see them called out in some specs. The manufacturers' pitch is that it's "non-metal" and "fiber-based" to make it safe around electrical installations. I see the installers are tying the 145P on things and then printing out a label on their label printer to stick onto the 145P tag. If the printed label is acceptably "non-metal" and safe around electrical equipment, then why did you need the 145P tag? Why not just print out a wire marker label? I'm speculating that these come from a time when you couldn't just print out a plastic label on demand, and you could tie this onto the cable and write on it with a marker, but I have no basis for that other than they don't seem to make sense any other way. -Adam
