ABSTRACT:
An apparatus and method for straightening warped doors of a residential type includes an elongate member anchored at opposite ends to the top and bottom section of the warped door. Means are provided for adjusting the length of the elongate member to create tension along the length of the door. Spaced pressure blocks slidably maintained along the elongate member rotate about the axis of the elongate member for selectively pressing against the warped surface of the door. Contact of the spaced pressure block means with the door increases tension on the elongate member which in turn exerts increased force against the spaced pressure block means and provides maximum efficiency for straightening the door.
