These are the cage nut tools:


But these rackstuds - very interesting. My main concerns would be vibration chewing through them over the span of weeks/months/years. Also they would interfere with cable management being that they stick out so far. For example you might not be able to use the Cisco cable management things that usually come with 2 and 3k series switches.

Plus I would imagine the cost is considerably more expensive - at about 66c each, that's $5.28 per U. For a typical rack with lets say 15 devices, thats $80 per rack.

I suppose most NZ businesses never have more than 1 rack so cost isn't too bad.

Thanx for the info..

Cage nuts can now go and stick it.

I don't care what anybody says those cage nuts tools are freken useless. All the big suppliers give them out with their cabinets and they are crap. I am sick of cutting fingers and dropping the bloody things.

Will be ordering thousands and never going back.

Thanks to the OP!!!

That is a thought, I wonder if they've considered that into their testing?

I'm sorry but pebkac here. They work fine. Haven't had a cut finger since discovering these things several years ago.

Thanx BTR for suggesting these. I passed it on to our installers who promptly ordered a box of 100 unites.. :-)

I tried them for the first time this morning.... pretty amazing, but I'm not sure I'd want a 50kg server hanging off these things lol

Hi there,

I'm the inventor of the Rackstuds™ based in Birkenhead. I used to be an installer in the security industry and I thought of these 13yrs ago after trying to get a 16kg computer in a rack on my own. Way too hard and ending up stacking telephone books underneath the computer to get it mounted with cage nuts.

Even though we rate these to 20kg for all four studs, the shear strength per stud is well above that (213kg random batch test last week). We had to put a limit though to keep legal happy. If you have equipment that mounts front and rear (like a shelf), loading these up beyond 60kg would not pose a problem.

Long-term slow vibration and creep should not be an issue as they are not made from any ordinary plastic and instead are engineered from a 'metal replacement' plastic that is extremely hard. If you try and compress the spring section, you'll see it behaves exactly like metal.

Happy to answer any questions and if anyone knows of a Rack Manufacturer that does in-house testing for Seismic 4, I'd be happy to supply Rackstuds™ for their next test as there is no specific test we can do in Australasia based on conversations with SGS and UL.

What does this tag do

Quite tempted to order a box from Acquire, but for seismic purposes (new medical facility in Christchurch) I feel like might be safer sticking with the traditional option for now.. maybe for lighter equipment but not my servers

I understand the shear strength is very impressive. However I am quite interested in the lateral or push/pull strength.

Reason being is that the recent Wellington earthquakes highlighted how important this is, as some vertical rails were bent quite impressivly by the push/pull movement at the point where the cage nuts were mounted.

@Jeeves,

If you play the video at the bottom of this page (http://www.iso-base.com/), you'll see the type of waveform that gets input into a shaker table for seismic testing. I sent this to UL and they advised that based on the testing we've done with them, the Rackstuds™ would likely survive this as it's at 1.5Hz for 30s. I'm working with overseas rack manufacturers to have the Rackstuds™ included in a testing run so they get 'grandfathered' down as compliant as there is no actual test performed on cage nuts specifically and no testing data for them. It's just assumed they were used as the mounting solution for the test cabinet.

Ordered some from Aquila to give them a try. The idea looks fantastic, hopefully they live up to it as Ive got a massive datacentre move to do next year.

Works great!!!!!!!!!!!

Took a while to get all the old standard cage nuts out but well worth it!
