This is a pair of arms that hold an iPad (iPad Pro 12.9 in my case) over a Peloton Tread+ 1st gen screen. Saw lots of models for the Bike but not many for the Tread+. I added 1" width felt tape on the backsides to avoid creating scratches on the screen. Initially, I was just setting the iPad on the tray but the height is too low for watching shows comfortably.
