I was recently watching an episode of TOL (don't know if it was a repeat or new) in which one of the guys made a "hidden door" to go to the basement. Instead of normal hinges, it had pins at the top and bottom. It was a full-height door, not a cafe style seen in restaurants. Anyone know where such hardware can be found? I can't find them on the net. I want to use them with double swinging doors for a 28" door entry to a small laundry room where there is insufficient clearance inside and in the hall for a single door. She wants solid full-size doors, not bifold or slatted doors nor those thin closet doors.
