If you don't have the proper rails for the servers and UPSs, I'll echo Lennart's recommendation of https://www.rack-solutions.ca/ (I've purchased from their US store before the Canadian site existed). You can search on ebay for rails to match your servers, but they are likely expensive, if you can find them. A generic shelf or universal rails is often a better choice. | > I find the main trouble is known what kind of screws a specific type of | > rack needs.

My experience says that the most common screw/bolt for racks is 10/32 (see Home Depot). Some cage nuts are 12/32(?) I think. If the rack has square holes, many things mount tool-less. If you need cage nuts, I'll suggest Newark as "reasonable". Hope that helps! John
