I had fun with these Bifold Closet Doors for friends from church. Their bedroom had no door to the family room so when the early morning sun would come into the family room windows, they would be rudely awakened. Also when they had visitors, they had no privacy. As a solution, we used typical louvre doors between the two rooms. As you can see from the video, it is a very easy task. Because of the varying widths of the doors, we could accommodate the size problem.
Easy to adjust and align by visually looking at each bi fold door when closed. Adjust by either moving the bottom pin or adjusting the screw in the top channel.
If parts are missing and/or they don't stay in place, bifold door parts are available at Home Depot, Lowe's, Ace Hardware or any other Hardware Retailer.
