I have these small metal tags for tagging RUGF cables. I offer to mail these cost free to someone attempting to make up a super original RUGF installation. I think these quite small flat tags are intended to be bent in a circle around equip cables. They kinda remind me of bands you would use to band a bird leg, but larger.
