Every ARCvault 48 comes with a tray-style Rack Kit that 
allows you to easily install and remove the unit without 
having to engage side rails. The Rack Kit includes all 
mounting hardware.

WARNING:  It is recommended that a mechanical 
lifter (or at least two people) be used to raise and 
align the unit to prevent injury during installation.

WARNING:  Use care when inserting or removing an 
ARCvault unit into or out of a rack to prevent the 
accidental tipping of the unit causing damage or 
personal injury.

1. Locate and mark the holes for the rails and retaining 

screws:
a. Starting with the right front flange, at the bottom 

of the rack (or from the top of a previously mounted 
component), locate the first set (

) of three 

holes with equal gaps of 5/8 inch (1.6cm).

b. Mark the top and bottom holes of the set for the 

rail screws.

c. Mark the second and eighth holes above the set

 for the rear holes.

CAUTION:  

Be sure rear holes are horizontally in line with the 

front holes to assure the unit remains level.

3. Adjust the rail rear brackets to fit the rail inside the 

rack flanges:
a. Remove and retain the two adjustment nuts and 

washers on the right rail.

b. Move the rear bracket so that the PEM studs are 

in different slots (

) based on the rack size.

• For a 36" rack, use the two front slots.
• For a 30" rack, use the two center slots.

 for the left rail.

notches must face outside, away from the rail.
