Fixturing Question

I need to fixture some small diameter wires , (0.013") for coating. These parts are small diameter, but they're moderately long, (60" to

84"). Also, by fixture, I mean hold both ends securely so I can spray them.

I've seen some fixturing that uses little "holders" that remind me of an iris or an iris valve to hold such small diameter parts. I've looked on line but can't seem to come up with the right component.

Does anyone know a way to hold such small parts? Ever heard of or seen the little "irises" I'm referring to? Any helpful input is appreciated.

Thanks!
