Yeah, I thought of glue too. I'm sure it works perfectly but if you have to remove board later... I'm thinking of the same thing as tangent, having pcb-mounted pot be also mounted on the panel, and that is keeping the board in place, but I would like more support... something like a stopper in the rail would be nice but I have no idea how to do that. Hm... use glue as the stopper, to create a tough spot in the rails, NOT to actually glue the PCB to the case! Doh.
I ordered 1455K1601 which is a bit smaller - 81mm x 35mm , though still the same 6" length, and with metal panels. N1601 is the next size and is a bit more expensive. I wasn't commenting on price, just was surprised that somebody already has some. I have a habit of talking when I shouldn't and then people misunderstand me (or even worse, take my words for the complete opposite, so I have to go around telling people I wasn't insulting them at all). Something like Hagrid (Harry Potter overload). Oh, and I STILL didn't receive promotion (500+ member!).
