Equipment Installation
Installing or Removing Cage Nuts
WARNING: The flanges of the cage nuts should engage the sides of the square opening in the rail, not the top and bottom. Follow the instructions in your
equipment documentation to ensure proper installation of your equipment.
Installing Cage Nuts
1
Locate the numbered square openings in the mounting rails where you plan to install your equipment. You
will install cage nuts (included) into the square openings in order to provide an attachment point for the
mounting screws (included). Note: Consult your equipment documentation to determine how many cage
nuts will be required and where they will need to be installed.
2
From the inside of the mounting rail, insert one of the flanges of the cage nut through the square opening.
Press it against the side of the square opening. Each flange should engage one side of the square opening,
not the top or bottom.
3
Compress the cage nut at the sides slightly to allow the remaining flange to fit through the square opening.
When the cage nut is properly installed, both flanges will protrude through the square opening and will be
visible on the outer surface of the mounting rail. Repeat steps 1-3 until all required cage nuts are installed.
4
After installing the required cage nuts, use the included mounting screws and cup washers to secure your
equipment to the rack rail. Place the cup washers between the screws and the equipment mounting brackets.
Note: Your equipment may also include mounting hardware. Read the mounting instructions that came with
your equipment before installing your equipment.

Note: You may wish to use a cage nut tool (user-supplied) to aid cage nut installation and removal.
