These are the dimensions and a rough diagram of what the structure looks like sitting from the far side of the couch.

The plywood frame comes out to about 4.75" from the wall at the thickest point in the centre. There's 23.5" between each side of frame. The door is attched by hinges on the side closest to the couch. There's a locking bolt on the opposite side that goes into the plywood. Between the door and wall of Boler is a strip of foam to close off all gaps.

I'm not sure if all Boler doors are the same dimensions, but this should give you a good idea of the concept.
 
 

My outer door swings all the way open and has a clip to keep it open and against the outside wall so it doesn't close. Here's a quick scan of my hinges to see if you think there's a difference.
