Fitting Instructions 
Thank you for purchasing this Adastra product, which has been designed to secure and 
protect your valuable Rackmount equipment. Please note that we recommend the vented 
version for any items which depend upon good airflow for cooling. When opening the 
packaging, please check that you have the following parts. 
1) Main cover 
2) Loop end bracket 
3) Tab end bracket 
4) Padlock with keys 
The next step is to repeat this process for the other end bracket at the other side. 
Finally, slide the flat end of the Main cover (1) over the Tab end bracket (3) and position 
the looped end of the Main cover over the Loop end bracket (2). 
You will need to remove the screws that secure one side of the 19” Rackmount 
equipment to be covered and position either the Loop end bracket (2) or the Tab end 
bracket (3) over this end and secure both together with the screws. 
The holes in the Main cover and Loop end bracket will align to allow the padlock staple to 
be hooked through and securely locked. The whole assembly will now be secure and all 
rack fasteners safe from tampering.
