Installation

1.  Make sure that the front and rear frames are right side up. The 

bottom of the frame has holes for the floor mounting brackets 

and casters. Make sure that the pictured end is at the bottom.

2.  Attach the arms to the frames. Separate your arms into pairs 

(consisting of one wide and one narrow arm per pair).You will 

have four pairs of arms, two for each side of the rack. The narrow 

arms that connect the bottom of the frames can be identified by 

the pre-mounted cage nuts on the inside of the arms.

NOTE: 

When installing the arms, it might be easiest to start with the 

top arms for stability reasons.

nuts

3.  For the top arms, snap the cage nuts into the back (inside) of the 

narrow arms. It is recommended that you install several cage nuts 

on each arm. The cage nuts are easier to install when the rack is 

not fully assembled.You should install more cage nuts than may be 

necessary in case you change the depth of the rack in the future.

4.  Determine the desired depth of your rack. Using two screws, 

attach one of the arms to the holes on the inside of the frame. 

Attach the other arm to the other side of the frame, making sure 
that the wider arm is on the outside of the narrow arm. Secure the 
two arms together using the provided screws.

NOTE:

 For stability, StarTech.com recommends that you have use at 

least 

two

 screws to secure the rack arms.

5.  Attach the floor mounting brackets (the L-shaped brackets) to the 

bottom of the frames. Using the included hex key, install the hex 

socket screws.  Install 4 screws per bracket.

WARNING!

 To prevent bodily injury, please ensure that the rack 

is installed in a structurally sound environment with a level floor 

and that all hardware has been assembled securely, and checked for 

stability before loading equipment. When installing equipment into 

the rack, start from the bottom of the rack first and move upwards, 

keeping the heaviest equipment at the bottom to avoid a situation 

where the rack becomes top-heavy.
