Kinda OT?: Looking for rackmount screw sets....

Well, I just acquired a 5' x 3' x 2' IBM AS400 drive cabinet. F--n heavy! Now, to mount equipment in it, I need to find some more of those clip-on T-nut kinda things, which clip on around the hole in the rails, so you then use the supplies screws to mount your equipment. Some older DEC racks used the same thing. And, as you can guess, the guys at the local Home Depot just gave me funny looks. Anybody know where I can get a dozen or two of these screw mount sets? For a reasonable price? And what are they called? --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818 Mac OS X 10.1.2 - Darwin Kernel Version 5.2: Fri Dec 7 21:39:35 PST 2001 Running since 01/22/2002 without a crash
