The present invention is directed to a frame that is placed at an opening portion in a partition provided in houses and the like, and specifically an adjustable frame comprising a plurality of frame adjustable fasteners including: a fixing member including an external thread member having a cylindrical manner for being incorporated at a partition side of an opening portion in a partition provided in houses and the like, and a base member for rotatably supporting said external thread member; and an internal thread member for being rotatably engaged with said external thread member and for installed in a frame body. The adjustable frame allows the external thread member to be turned, thereby adjusting its length, capable of fixing to the opening portion of the partition. Further, if necessary, the adjustable frame may be comprised of a pair of frame members having the width where a first frame member and a second frame member overlap in part in a thickness direction of the partition (wall thickness). It is provided a surface member so arranged that the end face of said second frame member that overlaps the surface of said first frame member and the edge surface thereof are covered, and a clip engaging member for allowing said first frame member to be brought into contact with the bark surface of said second frame member is also provided. In the above-mentioned arrangement, therefore, the adjustable frame can be adapted for the wall thickness of the opening portion. The adjustable frame can. be realized in a manner that the spacing between the partition and the frame can be readily adjusted by turning the external thread member at the time of installation of the frame at the opening portion of the partition provided in houses and the like, and can be adapted for different levels of the wall thickness by a separated frame member in a wall thickness direction of the opening portion.
