Review: 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

## Questions & Answers

**Q: What kind of plastic are these? pla, abs, or pteg?**
A: PLA, ABS or PTEG ain't going to cut it I'm afraid. While the bags are PTEG, the Rackstuds are made of Grivory, a metal replacement plastic often found in car door handles and wiper blade arms.

**Q: Which version of rackstuds will fit the startech 4u 19" desktop open frame rack?**
A: Sadly the holes on some of the Startech racks are too small for Rackstuds. Search Google for our post on this using Rackstuds and Startech as the keywords. You could try a sample pack that has both sizes/colors to test first if you like.

**Q: are the samples the same quality materials as the actual 100 Pack ? Or they are just guide for figuring out the sizes**
A: Thanks for your question. The samples are production parts and fit for field use. They just contain both sizes/colors along with eight nuts; four in black and four in turquoise so you can determine which size fits your rack best. In saying that, the new Series II Maroon studs fit 70~80% of the rails in the market.

**Q: any reason why I should use the yellow lockwasher?  It's hard for me to get them close together when I use those**
A: Yes, because it's designed to hold the Rackstud in an open position so it doesn't fall through the hole.  Just insert the Rackstud, place the yellow lockwasher on the correct way with the little extra bit facing the rack/Rackstud, mount your gear and then tighten the screw.  It will force the little yellow bit in place.

If you can't tighten it enough by hand use a screwdriver the first time to ensure proper seating of the yellow lockwasher.
