How to Install Bi-Fold Door Knobs

Bi-fold doors are a popular option for pantries, room separation and closets. The bi-fold doors pivot at the side and fold neatly against the jamb for full access through the door opening, without protruding into the room like a conventional swing door. The final step in the installation of your new bi-fold doors is installing the door knobs, and the simple procedure can be adapted to bi-fold doors of any size.
