Jeg synes Ikke de leverer hvad de lover har brugt dem i forskellige racks til både Mixer og Effektenheder samt Pa forstærkere der er store problemer med montagen, det er svært at få dem til at sidde korrekt og jeg synes ikke de har nogen hjælpende effekt
I have used these in many racks with both M5 and M6 screws. These ARE compatible with both M5 and M6 screws because adaptors are provided for M5 screws.
As noted by another reviewer the can get mis-shapen if you are not careful, but this has only been a cosmetic problem for me.
As for isolation, they have worked every time for me (tested). I have not had trouble keeping the faceplates isolated. Important: when testing for isolation/continuity, remember to unplug all of the power cables from power distribution unit to rack devices. Otherwise the meter will indicate continuity, since the devices are joined through the PE/ECC conductor of each piece of gear (and this is how it must be for safety - NEVER cut a ground/PE/ECC conductor.
