It's just a simple Satellite box mount.

If you're forced into changing your satellite hardware with Shaw/Rogers merger in Canada, this may alleviate some grief.

For some reason Arris removed holes for mounting the box to the wall. I prefer my satellite boxes mounted behind TV so designed this wall mount bracket to securely hold the box to the wall with 2 screws.
Cutout on the bottom alleviates any heat issues.

No supports needed on X1 Carbon.
