How to Install a Fixed, Block Door Frame - Interior Doors Fixed door frames are currently less popular, but they are practically the only alternative to adjustable door frames. The need to install a fixed (block) door frame often arises during interior renovations where builders didn't pay close attention to wall thickness or it was impossible to build an identical wall on both sides of the door.
