Secret Bookshelf Door

Bookcase is Mounted to Hidden Door and Supporting Wheel

This commercial bookshelf does not appear to be a custom installation of any kind. It sets out in front of the wall, different than many bookcase doors. However this one is mounted do a door with sturdy hinges, and supported with a caster. The downfall to using casters is that if the door sees too much use, the caster will wear a track on the floor or in the carpet.
