Generally ALL enclosure manufacturer make different hole positions and hole sizes for their enclosures.
That means... Frontpanels from manufacturer "A" will not fit on enclosures from manufactuer "B".
If you buy frontpanels, rearpanels and enclosures from us - everything will work fine of course.
But if you want to use any other enclosure it's a good Idea to order the frontpanel from us without enclosure holes.
Then you need to drill these 4 holes (which connects the frontpanel with the enclosure) yourselfs.
Sadly most of the available enclosures have rearpanels made out of steel - and not made out of aluminum.
That means that they're much harder to drill and it's impossible to engrave them because.
The problem: The steel will corrode at the positions where the cuttings and engravings are. (because of the missing powder coating)
