Abstract: A wall panel jack comprising a turnbuckle connecting a cradle shaft to a foot shaft, a cradle pivotably attached to an extreme of the cradle shaft opposite the turnbuckle, and a foot pivotably attached to an extreme of the foot shaft opposite the turnbuckle. The turnbuckle incorporates a turnbuckle bore with a turnbuckle bore cradle thread and a turnbuckle bore foot thread. The cradle shaft has a cradle shaft thread sized to mate with the turnbuckle bore cradle thread, and the foot shaft has a foot shaft thread sized to mate with the turnbuckle bore foot thread. The cradle incorporates a cradle groove sized to admit the lower edge of a wall panel, and the foot incorporates a foot pad made of non-slip material. Rotation of the turnbuckle varies the distance between the cradle groove and the foot pad.
