What is this?

Edit: Actually add an attachment

Hi,

Received my Gunfighter + MCG Pro today. Only just got it setup but I'm really impressed with it so far. Some of the components in the accessories bag are a bit confusing. I realise I'm probably being stupid but I can find no documentation or information on what this (attachment) is? There are also a number of what looks like plastic sleeves; what are they for?

Thanks in advance.

That is a cable organizer and gets installed on the back of the Black Box with 2 small self tapping black screws.

Ah, that makes perfect sense and I now see where that would fit. Thanks!
