[chbot] 19" rack rails...

[Chris Hellyar]

A bit of a random question, but figured this was the best place to ask. :)

I'm on the hunt for some standard 19" rack mounting rails....  The bits 
that go either side of the rack to clip the blind nuts into.

I want to make a customer rack/stand for some 19" gear by mounting the 
rails to some MDF.

So...

Anyone know where you can buy the stuff, or alternately, anyone got some 
old rack components lying around I can magpie? :-)

FYI: I need 10U high/long bits..

Cheers, Chris H
