This is the Rogue Jammer pull up bar, I pulled this image from the website as mine is still new in the box.

Here is information pulled from the site about it.

Designed to mount above a doorway frame on a standard wood stud wall*, the Rogue Jammer Pull-Up Bar is an everyday game-changer—enabling athletes to transport their fitness lifestyle, without compromise, into any room of their home or workplace.

The system, which includes a 43” long stringer, 0.375" thick laser-cut steel brackets, and a custom-finished 1.125" diameter bar, is on par with the equipment you’re already using at the local gym or in the garage. Only now, you can integrate part of that experience into your "between workout" hours—do a few pull-ups anytime you walk through that door; challenge family members or co-workers to do the same. Set the bar and stick to it.
