Toolless and easily installed

To mount the /dev/mount, you simply have to pass it through the 19″ rail from behind, guide the small lug through the middle hole and hook it there. Finally, the still open leg is pressed shut and holds the /dev/mount securely in place.

Easier handling for faster installation

To make mounting of hardware even easier and faster the /dev/mount comes with long reversible hex nuts, that can be used from both sides no matter how you hold them. Setting up a network rack can be an exhausting and sweaty job when not using a Setup.exe. Sweaty hands and tiny screws in uncomfortable positions are a bad combination – this takes up a lot of expensive time and can even lead to back-related injuries. The easier handling of our cage nut alternative speeds up the process of mounting 19″ equipment and is time and cost-saving.

M5 and M6 cage nuts have sharp edges and can be quite dangerous. Every technician knows the pain. Our /dev/mount is easily installed, and doesn’t require any tools. It is designed to be handled much safer. Our cage nut alternative can be softly and comfortably mounted onto the 19″ rail of the network rack.
