unfortunately I dont have a picture, and wont for a week or so, when I was hoping to go back and do the work.
It looks like a normal closet sliding door track secured to the ceiling with the double J track or whatever its called. But, it has 4 wheels on a carriage style roller set up, two on each side of the track, instead of just one wheel per roller.
It is not a pocket door, just two sliding doors on either side of the entertainment partial wall. There is no access compartment or removable panel.
