Captive nut and spring steel cage feature wings that can be compressed to snap into the square holes found in universal/punched panel rails. Unlike slide on cage nuts, this design locks the nut securely in place

Take away the hassle of dealing with stripped holes in tapped rails. If you strip a cage nut they can easily be replaced in the field, saving you time and money.

Using universal rack rails and cage nuts gives you the flexibility to use whatever size hardware you prefer. You can even use multiple sizes in the same installation. So now you can use smaller rack screws and cage nuts for lightweight rack shelves, cable managers, and spacer blanks, and larger hardware for heavier equipment such as servers, UPS’s and KVM switches.

The construction and materials used are better suited for threading than what is used in full size tapped rails. This provides a stronger, more durable fastening solution.
