Possibly the single greatest invention for IT workers since the on/off button

I will preface this review by saying that I was initially skeptical on ordering these as I have always used the standard nuts and screws that came with whatever hardware I was installing.Well I am now enlightened to the almighty that is Rackstuds, these are hands down one of the best products I have ever bought.No more getting my fingers shredded to pieces, an end to my hands being numb after squeezing various cage nuts into and out of place.These are an absolute dream and I have used them to mount various bits of hardware from 48 port PoE switches to shelves to patch panels.They just work, you clip them in, slide in the securing piece and screw on. They are as, if not more secure than the a nut and screw and they are much easier to install, move and remove when you are done.If ever you are doing a cab re-fit or a new install/tidy up, buy these, do not be lead down the "oh but the extra costs". Do it for your fingers and hands. You will not be disappointed

Simply amazing!

Such a simple and elegant solution, to what is a basic yet frustrating pain in any cabinet/rack build.Very impressed, just go a bit gentle with tightening them up at the end with Screwdrivers, too much torque even with basis unaided driver can damage the head, but once learnt this is easily overcome and doesn't reduce the effectiveness of the fitting.Great product, nicely done!

Love these... Way cooler than old fashioned rack screws...

Be aware that these are for proper square-holed rack rails and will not work with the new-fangled moulded racks which have round, threaded strips for bolting in your equipment. Square is the best and these bad-boys are awesome. They look cool and are cool!!!

Very happy

Have to say brilliant job

Cage nuts fit but Rackstuds on smaller racks with 0.9mm square holes do not fit

Couldn't for the life of me get these Rackstuds to fit. Useless to me.

Check your rack - not quite so “universal”

Didn’t work for either of my racks. Customer support was great but I wasted my money
