Adjustable door support and methods of use

A method of using an adjustable door support for acquiring a door gap and for supporting a door slab at a height off a floor equal to the door gap, the door gap defined as a distance between a bottom edge of the door slab pivotally mounted to a door frame through door hinges and the floor, the method comprising the steps of:

• providing a rectangular sheet of bendable material including two outer sections and two inner sections, the rectangular sheet having transverse pre-scored lines extending across the entire width of the sheet in a transverse direction to separate the outer sections and the two inner sections, and two longitudinal parallel cut lines extend across a portion of the length of the two inner sections in a longitudinal direction, the distance between the longitudinal parallel cut lines in the transverse direction being equal or larger than a thickness of the door slab;
• pre-shaping the rectangular sheet along the transverse pre-scored lines to form an inverted “V” shaped structure such that the two inner sections are disposed relative to one another at an oblique angle and form a support slot for receiving a portion of the door slab therein, the support slot defined by the two inner sections and having two opposite door support edges configured to engage the door slab;
• providing two tie devices, each of the tie devices including a cable tie and an adjustable locking washer;
• passing the cable tie of each of the tie devices through both of the two inner sections of the pre-shaped rectangular sheet;
• attaching the locking washer of each of the tie devices to a free distal end of the cable tie of one of the tie devices by sliding over the cable tie to form a pre-shaped door support;
• positioning the pre-shaped door support under the door slab hung on the door frame so that the two outer sections are laying on a floor and a portion of the bottom edge of the door slab is disposed in the support slot of the pre-shaped door support;
• acquiring the door gap by pulling the cable tie so that the support edges of the door support are raised to engage the bottom edge of the door slab;
• locking the door support into shape by pulling on the cable ties and using the locking washers to lock the door support once the support edges of the door support reach the height of the door gap.
