I have multiple Norco RPC 4224 4u cases. but the rails from Norco Suck! As in the don’t fit a standard rack (with wise, which is weird) I would also like to put them on some other cases even if I have to drill some holes/Rivnut.
I have not found any aftermarket ones that we love, they never seem to fit just right. We install a lot of these as they make it easy to just set the server in. Not as nice as the roller bearing slide rails but they get the job done.
Yes I have a few of those was hoping to find a Universal sliding one. As you said, I have yet to see one that is on the level as the ones that come with Dell/HP/Super micro servers
