One of the challenging projects in carpentry is building a hidden bookcase.
Hidden bookcase doors are more complicated that other ordinary doors. This is due to the variations in their designs and construction, especially on the openings that have to swing out.

This calls for some adjustments and a lot of jamb clearance as time passes by. Wheels and rollers can be used to support the swinging book case at the bottom. The floor needs to be smooth and hard.
When using a roller, you have to remember to leave a gap between the bottom of the door and the floor clearance.
