Hello: I don't know what you would call them, but what is the trim around a panel meter called and where would you find one. I would like to put some kind of trim around a KNIGHT T 60 transmitter's panel meter I am restoring. That would really make it look good. Like the HEATH DX 60 panel meter.

Thanks John

Hi John...   I have heard the word "escutcheon" used in that sense.  But I think your project sounds as if it could benefit from a collaboration with some kid who plays with 3D printers.  Every job will be a bit different and "nobody" makes those meters like the T-60 had.    I remember the fun of looking through the radio catalog, close to an inch thick at the time, and seeing the T-60, and the even more unattainable T-150.  Having a hot rodded version would add to the coolness factor.  One of my fellow hams back in high school had one and even had a Rat Fink figure sitting atop it, if you can remember back that far.  It didn't take much to amuse us at the time.

Sometimes this stuff works and looks  well as trim. Google gives you lots of choices, colors, styles, etc.
Black Car Door Moulding Rubber Scratch Protector Strip Edge Guard Trim

OR, just use some black tape strips around the edge of the meter opening.

They sell extruded rubber in the |_| profile in a variety of sizes, smaller than the auto trim.
One place is the screen and window industry.

A lot depends on exactly what look ur going for.

One can make stuff up using metal, with just a drill press and elbow grease too...

There is also the epoxy molding compound used typically with fiberglass fabrication.
That can be colored easily (like black) and a mold can be made using this latex mold
stuff they sell in the hobby stores.

Check yoohootoobe to see examples of molded parts made this way, and with other
materials.

Heck, you can go all the way and mold with metal!
Zinc is a best bet!
So called potmetal is mostly zinc. Low temp melting point.
One guy I saw was melting pennies to get zinc, and skimming it off, leaving the
copper behind... same process with the latex molding goop, just a different final
mold material!

etc...

So, what sort of "look" are you aiming for?
Is this a replacement of a stock bezel?

If the question is FINDING them, which it appears to be, I'd say unlikely. If it is MAKING them, the the possibilities are endless. Consider balsa wood, Sealed and painted, no one would ever know and it's easy to work.

For the rubber trim idea, check McMaster-Carr. They have many sizes and sell it in reasonable lengths for around a $1 a foot.

I have heard it referred to as a Bezel and meter manufacturers like Modutec sell it as a separate item to go with their meters when they are recessed behind a panel.
