Rackstuds Smart Rack Mounting System, 2.7mm Version, 100-pack

tried these with a standard size / weight Cisco router, and it didnt hold the device level as the normal metal cage nuts do - would be fine for lightweight devices im sure

These are amazing. Had issues initially as bought the smaller gauge red variant and these did not fit our 10 year old APC racks (newer ones are apparently made with thinner gauge of metal).They are so much nicer and easier to use than traditional cage nuts and bolts. Initially the folks from our networks group were sceptical but were delighted to have been proven wrong. Everyone shown the system from that point onwards has said that it was a real revelation. New data centre fully racked out in a fraction of the usual time.We are now considering making this a standard in our company!

They work as you would expect, only they make life so much easier. Switch to them, you'll thank me.

The idea is great, the usefulness is equal to zero.
