Sign cabinet framing information needed

[Stormyj]

Hi all,
I am working on a cabinet sign with several spaces for blank inserts. The inserts are slid into grooves in the cabinet. Very typical construction. What I need to know is where do I get the metal pieces that the inserts slide into. I have attached a pic of what Im talking about. Thanks all.

usually it's just one and a half inch or two divider bar, a extrusion you can pick up from a supplier who carries signcomp or others.....comes in 25 foot lengths or longer...

signcomp has an extrusion for that
