Wire & Terminal Block Numbering

[Elihu]

I've been building control panels & enclosures for years, but have never solved the problem of having my DIN rail terminal block numbers fade away after a few years. It's always light getting into control cabinets that fades the T-block numbering - inked by hand onto the blank marker cards w/ultra-fine lettering pens. Wire numbers made on my Brady ID Pal last fine - but operators open some cabinets, then don't close them fully. Pre-printed marker card sets don't work -- I'm modifying, upgrading, changing existing panels - only custom numbers assigned on-the-spot will do. Anybody have a solution?

For wire numbering it is hard to beat a hot-stamped or thermal transfer tube. They can stand up to a lot of punishment and be readable for years.
