Why you can't insert Rackstuds in any ol' hole

A closer look at why you can't just insert Rackstuds™ (or cage nuts) in any ol' hole and how to define the start of the 'RU' spacing as used in EIA-310 racks. When I first started out many years ago, I must admit that I didn't know that the holes were in matched sets of three! Introducing the all new Series II Rackstuds™. The Series II is a culmination of two years of development and testing in an effort to make the Rackstuds stronger, easier to insert and more tolerant of racks with thicker rails. Mission accomplished! • Longer Studs: Makes hanging easier when the gear has thicker ‘ears’. • New Nut: Added PZ2 screwdriver slot and finger flutes. • Redesigned Studs: Now even easier to insert. • Stronger: At least a 30% improvement in leverage tests. • More Tolerant: Now fits even thicker rails*. Purple version With over 1.5 Million units sold, the Series II Rackstuds builds on this reputation and ensures you can rack your gear faster, on your own and without hurting your fingers. Save time and money and up your sysadmin game. Say goodbye to cage nuts and say hello to Rackstuds Series II.
